I happen to have a GameBooster, a Gameboy adaptor that plugs into the PSX's parallel port. It also has a built-in game that plays if no cartridge is plugged in.outsideinsidebox

Similar/identical devices exist under names like Super GB Booster
, Super GB Booster Plus
, and Gold Finger 3-in-1
. There's also another device called "GameBooster" for the N64.
Is anyone interested in adding this to MESS? If anyone in Australia is willing and able to dump it I'll happily send it.
