AMOAD (Arcade Machine On A Disk) A collection of single emulators that each fit on a floppy disk. Binaries for AMOAD 20+22 are missing (they need re-compiling with Allegro v3.0 and SEAL v1.03).
ASIE (Amiga Space Invaders Emulator) It works only with GFX-Boards and the RTGMASTER library on an Amiga with an 040 or 060. Sound uses the AHI device.
MultiPac You can run any Pac Man clone, even if it isn't directly supported. For example if you have six roms called foo.5e, foo.5f, foo.6e ... foo.6j, just create a directory named "foo", put the roms into it and launch the emulator with "pacman foo". Grew up to become the amazing emulator that is MAME.
