32X + CD Games

There are six games that required both the 32X and the Mega-CD. These games are: Corpse Killer, Fahrenheit, Night Trap, Slam City with Scottie Pippen, Supreme Warrior, and Surgical Strike.

These games are released on a CD medium, and should be put in the megacd or segacd folder so that they show up correctly, since they use CD style ROMs.

You’ll need to change the emulator for these games to picodrive, as genesis_plus_gx does not support 32X games correctly.
