Arcade Party Pak^[1] (specifically, "720 Degrees", "Super Sprint", and "Toobin'" all are unplayable. "Klax", "Rampage", and "Smash TV" work like normal.)

Fighter Maker^[1]

Mortal Kombat Trilogy^[1] (only the "Greatest Hits" version (Platinum version in PAL regions) works on SCPH-50000, but even then the game freezes when the player wins the arcade mode)
