Kega Fusion Tutorial

Last updated September 22, 2020


About Kega Fusion

This tutorial is to help you with Kega Fusion for Windows. It was created by the famous Steve Snake in 2005. Steve created the first popular Genesis emulator, KGen, back in 1997. Kega Fusion is a top emulator, supporting a wide range of systems. The supported systems include Sega Master System, Game Gear, Genesis, Sega CD, 32X, and Sega CD 32X. And each system is emulated great, offering near-perfect game compatibility.

I think the coolest feature of Kega Fusion is its Sega CD 32X support. It's the only emulator that supports it. This is a real treat for hardcore Sega fans who want to play every Sega system, including the obscure ones.

*If you would like to download Kega Fusion, I have it on my emulators page.

Should you use Kega Fusion?

With all the emulator offerings as of 2023, should you use Kega Fusion? Well, it depends. The current #1 Genesis/Mega Drive emulator (regarding accuracy and compatibility) is “Genesis Plus GX”. It also supports Sega CD/Mega CD. However, Genesis Plus GX is not available as a standalone emulator and can only be used in multi-system emulators such as RetroArch and BizHawk.

Gens/GS has always been a strong competitor to Kega Fusion. Not everyone is fond of using multi-system emulators, so many people are still using Gens/GS or Kega Fusion despite knowing Genesis Plus GX is the superior emulator. When it comes to Kega Fusion versus Gens/GS, people generally prefer Kega Fusion.


Kega Fusion is a standalone program, so it does not have an install wizard. Installation is simple: just extract Kega Fusion from its zip file. Not sure how to extract zip files? Here's a video tutorial showing you how: how to unzip files on Windows.

IMPORTANT! Kega Fusion must be placed in a common folder on your computer. I recommend Documents, Downloads, or create a folder on your desktop. If you place Kega Fusion somewhere else on your main C drive, then you may be restricting it to read-only access. Doing so prevents Kega Fusion from saving anything.

To open Kega Fusion, double-click on Kega Fusion's EXE

Setting up the keyboard or gamepad

  1. Click on Options > Set Config, as shown here . Then click on the Controllers tab. You'll end up here:
    Kega Fusion's Keyboard/Gamepad Configuration
    Normally in these screens, video game emulators tell you which button is associated to which keyboard key. Kega Fusion doesn't. Instead of slapping around the keyboard to figure out which button is which, I recommend taking this moment to reassign buttons to keys you're comfortable with. Or configure your gamepad if that's what you're here to do. You can't use both the keyboard and a gamepad. You need to decide on one. Also, note that “Port 1” is Player 1 and “Port 2” is Player 2.
  2. The first step in configuring the keyboard or a gamepad is to decide on the controller type. The Genesis had two types of controllers: a 3-button and a 6-button controller. They looked like this:
    The Sega Genesis 3-button controller and 6-button controller
    By default, Kega Fusion is set to emulate the 3-button controller. You can change it to a 6-button controller by clicking on the drop-down selection next to Port 1, as shown here .
  3. If you want to configure a gamepad, first plug your gamepad into your computer. If Kega Fusion is open then close it and re-open it. Go back to the Set Config window. Click on “1. Keyboard” for Port 1 and select your gamepad. As so:
    Selecting a gamepad for Port 1 (Player 1)
    If your gamepad is not listed here, then it is not being detected by Windows. You need to troubleshoot getting your gamepad detected. Maybe your gamepad is too old or maybe you need to download a newer driver from the manufacturer's website.
  4. Time to configure the buttons. Click on the Define button for Port 1, as indicated below:
    Clicking the Define button for Port 1 to configure the buttons
    Kega Fusion will begin prompting you with directions. You will see these directions towards the bottom of the Set Config window. It will look like this:
    After clicking 'Define', Kega Fusion prompts you with directions on which button to push
    Press the keyboard key for the button you want associated with the button indicated in the prompt. If you're configuring a gamepad, press the gamepad button you want associated with the button in the prompt.
  5. That's it! Click OK when you're done. To configure buttons for Player 2, repeat the same process for Port 2.

Loading a game

*For loading a Sega CD game, visit the section in this tutorial dedicated to Sega CD.

Video game emulators typically have a dedicated “roms” folder. Kega Fusion does not. You can place the Sega ROMs you downloaded anywhere you want. You can place them inside Kega Fusion's folder or somewhere else. It doesn't require them in a specific location.

Here's how to load a game:

  1. Click on the File menu, as so:
    Loading a game in Kega Fusion
    Since Kega Fusion is a multi-system Sega emulator, you've got several options here. You can play Master System, Game Gear, Genesis, 32X, or Sega CD games. The next step is obvious: select the system of the game you want to play.
  2. The “Open” window will pop up. From this window navigate to the folder where your ROMs reside. Click on the game you want to play, then click Open - as shown here .
  3. The game will begin playing immediately.

Removing the annoying numbers

Kega Fusion's FPS indicator

By default, Kega Fusion displays numbers on the lower left. These are the frames per second. You can remove this visual annoyance by going to Options > Show FPS. While you're here, you should also click on Show SegaCD LEDs. That hides the annoying bars that display when playing a Sega CD game.

Full screen mode

To bring Kega Fusion into full screen, go to Video > Full screen. Or press Alt+Enter. And then to exit full screen, press Esc or Alt+Enter.

Q: 'Unable to set display mode' error!

When using Windows 10/11, upon attempting to enter fullscreen you may receive the following error message after an awkwardly long wait:

Unable to set display mode

Fortunately, there is a fix for this. Simply run Kega Fusion under Windows 7 emulation. Here's how:

  1. Right-click KegaFusion.exe and left-click Properties.
  2. Click on the Compatibility tab. You will end up here .
  3. Put a check in “Run this program in compatibility mode for”. Select Windows 7. Click OK. That's it!
  4. Lastly, there's a small annoyance that might happen upon setting Kega Fusion to emulate under an older version of Windows. From now on, every time you open it you might be prompted by this message: “Do you want to allow the following program from an unknown publisher to make changes to this computer?” Every time you will have to choose to accept that message.

Q: Kega Fusion crashes when entering full screen!

Although Kega Fusion is a top emulator, the fact still remains that it hasn't been updated in a long time. When using Windows 8 or Windows 10/11, Kega Fusion may behave funny or even crash when you jump into full screen mode. You should be able to fix this by using the Windows Compatibility feature to have Kega Fusion emulated under an older version of Windows. Here's how to set it up:

  1. Right-click KegaFusion.exe and left-click Properties.
  2. Click on the Compatibility tab. You will end up here .
  3. Here's the tricky part. I can't tell you what to do here because every video card is different.
    • You can start by clicking Run compatibility troubleshooter and follow the wizard. Try “Try recommended settings” first. If that doesn't fix it, try “Troubleshoot program”.
    • You could also try running Kega Fusion in compatibility mode under Windows 8 & older under “Run this program in compatibility mode for”. Probably Windows 7 or (even older) Windows XP is your best bet.
  4. Lastly, there's a small annoyance that might happen upon setting Kega Fusion to emulate under an older version of Windows. From now on, every time you open it you might be prompted by this message: “Do you want to allow the following program from an unknown publisher to make changes to this computer?” Every time you will have to choose to accept that message.

Save states

Save states is a feature that saves the exact spot you are in any game. You can use this feature manually by going into the File menu or by quick keyboard shortcuts.

Using the save state feature via the File menu
  • Capturing a state: To capture a save state go to File > Save State. The keyboard shortcut for saving a state is F5.
  • Loading a state: To load a state you previously saved, go to File > Load State. The keyboard shortcut for loading a save is F8.
  • Ten save slots! Kega Fusion allows you to save up to 10 different save states. By default it is set to slot “0”, the first slot. You can change the slot by going to File > Change State Slot. The keyboard shortcut for switching between slots is F6 (backward) and F7 (forward).

*All the RPG shrines in my offer complete collections of periodical game saves. With them, you can continue at any significant point in the game. I offer a Game Saves Tutorial where you can learn more about how to use somebody else's saves. You can also learn about how to transfer saves between other emulators.

Capturing screen shots

You need to make some small tweaks in the configuration before you start capturing screen shots. Go to Options > Set Config, then click on the Extras tab.

The options for screen shots

There are three things you need to set here:

  1. In the “Folder” field, click on Browse and set the destination where you'd like the screen shots to be saved to.
  2. Under “File Format”, select BMP unc. This changes the screen shot file format from TGA to BMP (bitmap). This is important because TGA is an obscure file format that isn't commonly supported. BMP, however, is a standard format supported by everything.
  3. Under “Output Stage”, select Raw. Selecting this is essential because it saves screen shots in their correct 1:1 aspect ratio and without filters applied. Click OK when you're done.

Finally, to save a screen shot just go to File > Save Screenshot. You could also press Shift+F12.

Recording AVI movies

Want to upload your own gameplay videos to YouTube? Well Kega Fusion will let you capture them! Here's how you do it:

  1. Open the game you would like to capture from. Play the game up to the point you want to start recording.
  2. Go to Video > Log AVI File, as shown here .
  3. You'll be prompted for where to save the movie and what to name it. Choose a location, enter a name, and click Save - as shown here . Kega Fusion will immediately begin recording.
  4. When you're finished recording, go back to Video > Log AVI File and you'll see a “AVI Logging Stopped” message on the bottom right of the screen.

Converting AVI movies

YouTube won't have a problem playing your video after you upload it. But, yet if you want to edit your AVI recording in a video editor, it might be rejected and not work. In that case, just convert your AVI recording to a more compatible format such as MP4. A great, free video converter is Miro Video Converter. With Miro, all you need to do is drag the AVI over to it, select Format > Video > MP4, and click Convert.

Using Game Genie & Pro Action Replay

The Game Genie cheats window
  1. First load the game. Click on File > Game Genie / PAR.
  2. In the “Code” field type the code. You could also Ctrl+V to paste it from a website. There cannot be any spaces in the code!
  3. In the “Description” field type a short description for the code.
  4. Click on the Add Code button to add the code.
  5. Repeat the process to enter more codes. Know that Kega Fusion does support cheats with multiple lines. You need to enter such codes one line at a time, and in order. Click OK when you're done.
  6. Reset or reload the game. If the cheat doesn't work then you either typed it wrong or it's a bad code.

Finding cheats: is a good site. The next best source is Google. The best search keywords to use is to type the name of the game then “game genie”. For example: “sonic the hedgehog game genie”.

Fast forward

Fast forward is the feature that speeds up the game. To access it, go to Options > Fast Forward. Or press the Backspace key to toggle it on/off.

Finding ROMs

In my links page, I have some good links to sites where you can download ROMs. If you want to try to find more sites than what's in my collection of links, just Google around. For example, if you want to download Sonic the Hedgehog just Google “download sonic the hedgehog genesis”.

Q: Can I transfer my saves to another emulator?

Unfortunately, no. I have not been successful transferring save states or SAV files (internal saved RAM) from Kega Fusion to other Genesis emulators. With SNES emulators, SRM files (internal saved RAM) can be transferred to any other SNES emulator. Genesis emulators, however, have not stuck to a similar standard.

At least, Kega Fusion isn't stingy with its saves as long as you keep using Kega Fusion. You can easily share your saves with other people who are using Kega Fusion. Or you can copy your saves for use on a Kega Fusion on another computer.

Q: Kega Fusion isn't saving anything!

If you're using Kega Fusion for the first time and you're finding that you have all these problems:

  1. Save states aren't working. You save a state, then when you try to reload it nothing happens.
  2. In an RPG when you save your game at a save point and close/re-open Kega Fusion, you find that the save is lost.
  3. Emulator configurations that you changed aren't saved. When you close/re-open Kega Fusion, you have to make those configuration changes again.

Then your problem is that you currently have Kega Fusion in a read-only location on your computer. You must move Kega Fusion to a more common location such as Documents, Downloads, or a folder on your desktop.

Intro to Sega CD emulation

There are some important details you should know about Sega CD emulation.

When downloading Sega CD ISOs

Sega CD games existed on audio CDs. The first track is the data, and the rest of the tracks are the game's soundtrack. When people rip Sega CD games to be placed in a ROM website for the world to download, the game is prepared in a similar data+audio track structure as the real thing. There are a few different types of formats that people have prepared ripped Sega CD games as. They consist of one or more BIN files (the game's data), audio tracks, and a CUE sheet. The CUE sheet is a simple text file with a programmatic list of the audio tracks.

The following are the four types of Sega CD ISOs. When you download a Sega CD game from a ROM website, it'll be in one of these formats.

  1. A binary BIN/CUE: As of the early 2020s, this is the new popular format being distributed from sites. It looks like this when you open it. All files are BIN files. When you look at the CUE sheet , the BIN files are organized as the audio tracks.
    • Important note: This new format is NOT compatible with Kega Fusion. It'll load, but the audio tracks will be out of sync. You need to use RetroArch (on Windows or Android) to run these games.
  2. A standard BIN/CUE: This is how video game ISOs (for any CD-based system) are normally ripped as. It looks like this when you open it. When you look at the CUE sheet , the audio tracks are listed even though there are no actual audio files present.
  3. An ISO/MP3: This used to be the most popular format for most of the 2000s and 2010s when the Internet was slower. Converting the audio tracks to MP3 significantly reduced the file size of Sega CD games. It looks like this when you open it. ISO/MP3 is supported by Kega Fusion and Gens/GS. However, other Genesis emulators don't support ISO/MP3.
  4. An ISO/WAV: This is an ISO/MP3 with the audio tracks converted to WAV. This format renders the game compatible with any Genesis emulator (that supports Sega CD).

In casual conversation on the Internet, all the above formats are referred to as a “Sega CD ISO.”

Internal saving is handled differently

The Sega CD RAM cart The Sega CD Backup RAM cart

Kega Fusion treats Sega CD differently than the way things work with the real Sega CD system. The real Sega CD system has internal memory (which doesn't hold much) and external RAM carts. However, Kega Fusion gives each game its own internal memory and its own external RAM cart. Cool, huh? That allows for a lot more space than the real thing.

There is one string attached, though. With the real Sega CD system, internal memory and each new RAM cart has to be formatted. And since Kega Fusion gives each game its own internal memory and RAM cart, you need to be formatting it each time you play a new game. That is, games that require saving such as RPGs. Some games won't even allow you to play them until the memory is formatted. But don't worry! Formatting is quick and easy to do. I explain the formatting process here.

Copies work on the real thing!

Yes, any Sega CD game that you download can be burned to a CD-R and played on the real thing with no problem. The Sega CD system does not have any kind of copy protection. In this tutorial, I have a section about burning Sega CD ISOs to CD-R.


You need to download the Sega CD BIOS to boot Sega CD games. There's a different one for each region. You can download them here:

Setting up the BIOS

Setting up the Sega CD BIOS
  1. Once downloaded, extract the bios from its zip file and place it in the same folder that Kega Fusion is in.
  2. Click on the Options > Set Config. Then click on the Sega CD tab (circled in the picture above).
  3. Click on the Browse button (circled in the picture above) for the Sega CD BIOS that you want to set. Navigate to the BIOS file, select it and click on Save. Click OK when you're done.

Loading Sega CD games

If you've been reading this tutorial since Intro to Sega CD emulation, then by this point:

  1. You have an understanding of Sega CD ISO formats.
  2. You understand how Sega CD handles saving differently than the real thing.
  3. You've downloaded & configured the Sega CD BIOS.

Now you can begin to load Sega CD games.

Loading a Sega CD ISO

  1. I'm assuming you downloaded a Sega CD game from a ROM site. Most emulation websites distribute their Sega CD downloads in a RAR or 7Z file. You would need to install 7-Zip (it's free) to extract the game from its RAR or 7Z file. Download & install 7-Zip. Once installed, you extract the game by right-clicking on it and going to 7-Zip > Extract Here, as shown here .
  2. If you downloaded an ISO/MP3 or BIN/CUE archive, it's important that it includes a CUE sheet. Sometimes they're not included. The game won't work without it. This is the CUE sheet . If it's missing, no worries. You can use this helpful utility, Sega CUE Maker (87 KB), to generate a CUE sheet.
  3. Open the CUE file in Notepad. And take a look at this screen shot . You are checking for the following:
    1. Make sure the name of the ISO matches the name of the actual ISO. It's okay if it's not case sensitive.
    2. Make sure all the audio tracks match the name of the actual audio tracks.
    3. Make sure all the audio tracks have the same audio format. If you have MP3 audio files, then the CUE sheet must show MP3 file types. If you encounter a CUE sheet that has WAV file types when the actual files are MP3, then within Notepad do a Find/Replace action to change them all to MP3.
  4. Okay! Now you can load the Sega CD ISO. Go to File > Load SegaCD Image, as shown here .
    • If the game is an ISO/MP3 or BIN/CUE archive, then you click on the CUE sheet to load the game.
    • If the game is just a single ISO file, then you click on the ISO file to load the game.
  5. The first screen you see when you load a Sega CD gameThe Sega CD BIOS screen
    The first screen you see is the Sega CD BIOS screen (shown to the right). Just press Start and the game will begin.
    *If upon pressing Start you see the CD player screen instead of the game, that's a problem. That means your Sega CD ISO is not valid. Review the steps above to ensure everything is correct. If all else fails try downloading that game from another ROM site.

Loading a real Sega CD or CD-R copy

First, I want to try to discourage you from trying to play a Sega CD game via your CD-ROM drive. The process is prone to have problems and you will experience slow loading times. Rather, what I do recommend is ripping your Sega CD game to a BIN/CUE. There is plenty of space on your hard drive for it. Plus it's good to have a digital backup of your game, just in case your physical copy gets lost or broken.

Here's how to load a real Sega CD game or CD-R copy:

  1. Insert the game into your CD-ROM. Wait a brief moment for Windows to load it. Close the “What do you want to do with this CD?” window if it pops up.
  2. Make sure your CD-ROM drive is set with Kega Fusion. Go to Options > CD Drive and click the name of your CD-ROM, as shown here .
    *If you are using an old version of Windows (Windows XP, Windows 98, Windows ME) and Kega Fusion is not detecting your CD drive, try installing ForceASPI.
  3. Go to File > Boot SegaCD. Wait a brief moment for the game to load.
  4. The first screen you see when you load a Sega CD gameThe Sega CD BIOS screen
    The first screen you see is the Sega CD BIOS screen (shown to the right). Just press Start and the game will begin.
    *If upon pressing Start you see the CD player screen instead of the game, that's a problem. That means your Sega CD game is not valid. If it's a CD-R copy, then it is bad burn. If all else fails try downloading the game.

Now that you have your Sega CD game running, it's very important that you read the next two sections about Perfect Sync and formatting the memory.

Perfect Sync

You must know about Perfect Sync!! It's a feature that tells Kega Fusion to give fewer commands with the emulation of a Sega CD game. Some Sega CD games require this feature to be enabled or else they will lock up at certain points in the beginning.

For example, “Popful Mail” won't boot past the Sega logo unless Perfect Sync is enabled. There are more games like that. You might be asking “Well, how come Kega Fusion doesn't automatically enable Perfect Sync for the games that need it?“ I do not know. This is something we all have to live with.

To enable Perfect Sync:

  1. Click on Option > Perfect Sync, or press Ctrl+P.
  2. Now load your Sega CD game. If you currently have a Sega CD game running, you need to restart it.
    *Don't forget to remove the check from Perfect Sync when you're done playing that game. Having it enabled with games that don't need it may cause problems.

Formatting Sega CD's memory

This process is necessary for RPGs, and maybe some non-RPGs. It's essential to do this if the game gives you a “Backup RAM not initialized” error.

  1. At the Sega CD BIOS screen , press the button you set for B.
  2. The CD Player screen on Sega CD The CD Player screen on Sega CD The Sega CD memory management screen The Sega CD memory management screen
    You will arrive at the CD Player screen (shown to the right). Move the hand to OPTION and access it.
  3. You will arrive at a screen with some memory info, just continue.
  4. You will arrive at the screen where you can manage your memory (shown to the right). First format internal memory by going to Format Sega CD.
  5. Choose Yes to format.
  6. Next, format the RAM cart by going to Format RAM cart.
  7. Choose Yes to format.
  8. Now choose Exit.
  9. At the CD Player screen, choose CD-ROM to boot the CD.

CD Swapping

Some Sega CD games are two CDs such as Ground Zero Texas & Night Trap. When it comes time to change discs, you should see a flashing CD tray icon in the bottom left of the display. This means the emulated CD tray is OPEN. You can safely load a second Sega CD ISO (or swap a CD) at this point. That's it! It's very easy.

Removing Sega CD LEDs

The Sega CD 'LED' lights in Kega Fusion

The Sega CD system has two lights that blink with when it's processing: a green 'READY' light and a red 'ACCESS' light. To make the Sega CD emulation experience a bit more authentic, these lights are indicated on the lower left of the screen. Personally, I find them to be distracting. You can remove them by going to Options > Show SegaCD LEDs.

Q: I get a 'Backup RAM not initialized' error!

You need to format the memory.

Q: My Sega CD game freezes in the beginning!

You need to enable Perfect Sync.

Q: My Sega CD game isn't playing music!

Read through the section about loading Sega CD games. Pay attention to the parts about verifying the CUE sheet.

Dumping your Sega CD games to ISO

Perhaps you prefer using your own Sega CD games instead of downloading them from the Internet? Or maybe you just want to keep backup copies of your Sega CD games? Whatever the case, here's how you can dump your games:

  1. Download & install RetroArch for Windows. It's the #1 multi-system emulator. I have a tutorial for RetroArch for Windows as well.
    • Note: During RetroArch's installation, setting a custom destination for RetroArch matters. It'll be easier for you to find RetroArch if you select an easy-to-find folder such as Documents. Otherwise, RetroArch defaults to your AppData folder deep in your C drive, which can be a little annoying to locate.
  2. Put your game CD in your computer's CD-ROM drive.
  3. Open RetroArch and select Dump Disc - as shown here
  4. On the next screen, select your CD-ROM drive (the first option, most likely).
  5. You're going to see this progress bar appear on the lower-left of the screen:
    Progress bar for dumping an ISO
    Depending on the speed of your CD-ROM drive, this will probably take 5-20 minutes to finish.
  6. When RetroArch finishes dumping your game CD, the progress bar will disappear. It doesn't prompt you with an alert sound or anything. If your CD-ROM was humming during the dumping, you'll know RetroArch finished when your CD-ROM's humming sound stops.
  7. RetroArch dumps the ISO of your game CD in its Downloads folder. So the next step is locating the Downloads folder. This is why in step #1 I noted to install RetroArch in an easy-to-find location. If you installed RetroArch in, say, your Documents folder, go to Documents > RetroArch > Downloads to find your game CD's ISO file. Otherwise, RetroArch is in the AppData folder. Here's how to find it:
    1. Open the Windows File Explorer. The easiest way to open it is to click the folder icon in your home row of apps. If a folder icon isn't present, you can also do this: in the “Type here to search” area type “file” and you'll see a File Explorer app appear at the top of the search results - as shown here .
    2. In the left panel, look for Local Disc (C:). Click on it, then in the main panel click Users - as shown here .
    3. Next, double-click on the folder for the user you are currently signed in as.
    4. In your 'user' folder, currently “AddData” is hidden. We need to make hidden folders visible. Click on View then Options - as shown here . Then click the View tab then click the radio bullet for Show hidden files, folders and drives . Click Apply then OK.
    5. The “AddData” folder should now be visible . Double-click on it. Then double-click on Roaming > RetroArch > Downloads.
  8. Now we're in the Downloads folder! You should see a BIN file and a CUE file with a weird filename like “cdrom-200000-1000000” - as shown here . Double-click on the CUE file and choose to open it in Notepad. You'll see the text that's shown in my picture.
  9. Next, rename the CUE file and BIN file to the name of your game. Open the CUE file in Notepad to rename the ISO as well. You can name these files to any name you want. The only requirement is that both files & the name in the CUE file must be the same exact name. Look here - these three instances need to be changed to the same name.
  10. That's it! You've successfully dumped your Sega CD game. You can use it with any Sega CD emulator or any multi-system emulator that supports Sega CD.

Burning Sega CD games from ISO

These directions are for burning either a BIN/CUE archive or ISO/MP3 archive to a CD-R. As mentioned previously, the real Sega CD system does not have copy protection. You can play CD-R copies on it with no problem.

Must have a CUE sheet!

It is essential for the Sega CD game you are going to burn to have a CUE sheet . You cannot proceed without it. If it's missing, no worries. You can use this helpful utility, Sega CUE Maker (87 KB), to generate a CUE sheet.

1. Convert MP3s to WAV

If your Sega CD game is a BIN/CUE, jump to “3. Burning to CD-R”. If your Sega CD game is an ISO/MP3, then the MP3 tracks must be converted to WAV. You can do so quickly with an awesome free program known as WinLAME. You can download WinLAME here (1.5 MB). Here's how to convert MP3s to WAV with WinLAME:

  1. Open WinLAME. Click on the Open button button, look for the folder where the MP3s are, select them all, then click on Open. You should see the MP3s you selected listed in the white box. Click Next to go to the next screen.
  2. You'll arrive at the “Output Settings” screen. Under “Output Module”, choose Wave Output, as shown here . Click Next to go to the next screen.
  3. You'll arrive at the “Presets” screen. The default is fine. Click Next to go to the next screen.
  4. You'll arrive at the “Encoding” screen. Click Convert button to begin the conversion.

2. Edit the CUE sheet

  1. We need to open the CUE file and change all instances of MP3 to WAV. The CUE sheet is this file . Go ahead and double-click it.
  2. You've probably never opened a CUE sheet on your computer. Windows will prompt you with an “Open With” window. Choose Notepad from the list, like this: on Windows 10/11 , on Windows XP . If Notepad isn't showing, click Other Programs and it should be there on the list.
  3. So you'll have a Notepad window like this . Click on the Edit menu then Replace. In “Find what” type “.mp3” and in “Replace with” type “.wav” - as shown here . Take note that this is case-sensitive! If your wav files have “.WAV” instead of “.wav”, then you must type it in caps here as “.WAV”. Click Replace All when you're ready.
  4. I don't think this part is necessary, but I like to do it anyway just so things are consistent. Do another Replace to change instances of “MP3” to “WAVE”. Your finished CUE sheet should look like this .

3. Burning to CD-R

Now we can burn to a CD-R. Don't have any? They're cheap on Amazon! You can use a CD-RW disc, but CD-R discs have a higher success rate.

  1. Download & install ImgBurn (it's free). You can download ImgBurn from the ImgBurn homepage.
    *If you have an anti-virus such as AVG, it may flag ImgBurn for containing adware . Don't panic - it does not contain adware! This warning is false. All that ImgBurn does is show you ads during the install wizard (which is why AVG falsely flags it). ImgBurn is 100% safe.
