32-bit console games I have with the emulators I got them to work with (which aren't necessarily the only ones or the best ones):
Playstation shooters (Mednafen):
Parodius: Chatting Parodius Live - Forever With Me
Maybe Einhander - I don't think I had to leave out any controls on my 6-button layout, but I see I have a "cycle weapons left" button but no "cycle right" button, so maybe I sacrificed that one.
Zanac X Zanac Neo
Deamcast (Demul):
Marvel Vs Capcom 2
Project Justice
Gamecube (Dolphin):
Soul Calibur 2
Wii (Dolphin):
Tatsunoko Vs Capcom
