Bummer - NTSC CD32 here - But I am booting into PAL mode like I do with all of your games. Many do not launch at all (Including Donkey Kong) - and those that do seem to not start at all with the Joypad. No buttons allow the games to start, although the joypad is perfectly responsive when choosing a game from the initial launcher. I do have a TF 68030 accelerator with 128 MB of RAM in there - I suppose I will try it without it.
Anything I can try?
Just an Addendum. I tried the ISO file on WinUAE emulating a CD32 (PAL) and have pretty much the same results.
Donkey Kong sticks on black screen with "1 UP" displayed. Galaxian you cannot see any sprites until they start moving, then they vanish. Ms. Pac Man and Pacman seem to load, but there is no button that starts the game. Phoenix does nothing but a black screen. SO far none of the games work on my real or virtual hardware.
