The new Game Boy Enhance model, the AGBM-02, is finally here! This is a replacement board for the AGBM-01, and uses AA batteries. For the uninitiated, my Game Boy Enhance design is a circuit-level recreation of the original GBA - it requires the use of the original CPU, so it's not emulation! 🧵

Happy 25th birthday, Game Boy Advance! To celebrate, I am happy to announce the Game Boy Enhance is FINALLY here! The Game Boy Enhance (AGBM) is a circuit-level recreation of the Game Boy Advance. It uses almost all-new components, but still uses the original CPU - it's not emulation!
