Hi, from Tassie.
Winuae emulator rom-pack has recently added MAST Fireball roms to it's emulated HDD list. There are two versions - v0.4 and v2.0 (1990) included as two 8kb rom files. If your "Main Chip" is the rom then ok
Otherwise the roms may be able to be split and be transferrable to IC's if you are familiar with the rom burning software.
Roms attached.
