You will need a Super Nintendo emulator to play Treasure of the Rudras. You can download one from my emulators page. If you need assistance with any of the emulators offered on my site, check out my emulation help subsite: Video Game Emulation for Newbies.
Important note: Treasure of the Rudras uses a high-resolution font for all text. That means the font renders at a higher resolution than the game itself. With the Super Nintendo emulator you choose to use, make sure its output resolution is higher than the native resolution to avoid legibility issues.
This is the game pre-patched with the English patch. I'm saving you the trouble of patching the game yourself.
This is the Japanese ROM of the game and its English patch. I put these here if you insist on patching the game yourself. If you need help with patching, check out my patching tutorial.
