I’m excited to announce the project I’ve been working on for the last year and a half: Game Bub, an open-source FPGA based retro emulation handheld, with support for Game Boy, Game Boy Color, and Game Boy Advance games. Play Video: Game Bub can play physical cartridges, as well as emulated cartridges using ROM files loaded from a microSD card. Game Bub also supports the Game Link Cable in both GB and GBA modes for multiplayer games. I designed the hardware with a number of bonus features, like video out (HDMI) via a custom dock, a rumble motor, real-time clock (for certain games). Additionally, the hardware is designed with extensibility in mind, allowing future software improvements to expand its capabilities.
