A Super Nintendo emulator is needed to play Trials of Mana/Seiken Densetsu 3. 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.
Trials of Mana: 3-Players Edition
By default, Trials of Mana/Seiken Densetsu 3 only allows up to 2 players. This hack enables 3 players! It's just like the old days with Secret of Mana. Below you can download this hack pre-patched with Trials of Mana, pre-patched with the fan-translated Seiken Densetsu 3, or just the patch by itself. If you need help with patching, check out my patching tutorial.
