Requires BIOS files mpr-17933.bin and sega_101.bin to run. Place them in the firmware folder.
Only seems to work with bin/cue disc images.
No GUI. Drop the cue file onto mednafen.exe to launch.
It runs fairly well for the most part. You'll see/hear plenty of small issues here and there depending the game. I was most impressed when I popped Clockwork Knight 2 in and found that the sound emulation was better than in SSF! BGM and SFX both seemed to be correct.
For the life of me, I can't seem to get any games to display at the correct resolution. Mednafen just spits everything out at 320x240. Supposedly, changing ss.stretch's value to "aspect" in the config file will fix this, but it didn't work for me.
