Alfonso hacked the Gameboy Advance by moving its game processing and rendering to a custom cartridge, which contained a Raspberry Pi 3 with a PlayStation emulator.
If finding a way to play PlayStation 1 games on a Gameboy Advance was one of your 2021 resolutions, you’re in luck.
The Raspberry Pi allows Alfonso to stream any RetroPie-compatible game to the Gameboy Advance through the device’s link port.
Because RetroPie is capable of emulating a wide range of retro consoles from the Nintendo Super NES to the Atari 7800, Alfonso’s hacked Gameboy Advance is able to play far more than just PS1 games.
