Project Unity, created by Bacteria, turns Sega Master System, Neo Geo MVS, GameCube, Dreamcast, Saturn, Intellivision, Colecovision, Atari 7800, Turbografx 16, PlayStation 1 & 2, Mega Drive, NES, Super NES, Game Boy Advance, Nintendo 64 and Amstrad GX4000 into one big console.
The fact that this vintage super-console even works is a feat itself, but more impressive is the fact that Bacteria didn't use a single emulator or modern alternative to make it happen. To preserve the authentic gaming experience, only original console hardware was used to create the system. The exception to this would be Project Unity's custom power supply, which feeds the system all the juice it needs through a single electrical outlet.
Another interesting and undeniably clever feature is the Project Unity controller. Rather than starting a pile of original gamepads for each console, a single custom controller uses repurposed NES game cartridges containing different circuit boards for each controller type.
