Download the specially marked Saturn BIOS for Mednafen. You can download it from my emulators page. Hence, proceed with the following directions anticipating that your Saturn ISO may get rejected.

People will tell you “ Oh, well it's not working because you downloaded a bad ISO.” Yet your 'bad ISO' works fine on uoYabause and SSF. It especially likes to reject fan translated games.

There's maybe a 50/50 chance that Mednafen will reject your Saturn ISO. While Mednafen can emulate Sega Saturn games well (uoYabause actually does it better), Mednafen is plagued with poor ISO compatibility (not to be confused with game specific compatibility). And if you haven't already, you should read Setting up the keyboard or gamepad so you can actually play the game.

scph5502.bin - required for Europe-region games.scph5501.bin - required for North America/US-region games.scph5500.bin - required for Japan-region games.I mean, you don't need all three, you just need the BIOS for the region you want to play.
