Overview
"GEI Multi Game" refers to a rare, casino-style gambling/video slot arcade hardware system released around 1992 by Grayhound Electronics Inc. (GEI). It is widely catalogued in emulation circles under the MAME (Multiple Arcade Machine Emulator)
Unlike traditional home console "multi-game" bootlegs (like the NES/Famicom-based 35-in-1 pirated systems of the same year), the GEI Multi Game system was specifically targeted at commercial casino, gray-market bar, and amusement route vendors.
