About 7 years ago people discussed whether the then new Game Boy Advance could emulate SNES games. The general reponse was that the GBA would be able to emulate SNES when hell froze over. So came SNES Advance by Loopy and Flubba, and hell froze over. Sure it was slow and didn’t have sound, but it was proof of concept that it could be done.
People said the same thing about Game Boy emulation on the TI-8x series of calculators. Yet, calc84/calc84maniac recently released the first public beta version of his TI-boy SE emulator. And it even has sound.
The emulator works on some TI-8x calculators (TI-83+SE, TI-84+, and TI-84+SE) and has support for a small number of games, for example Tetris, Zelda - Link’s Awakening and Kirby. Even if it’s slow, and sometimes glitchy it’s an amazing feat. I would definitely dub this the coolest TI calculator project of this year. (Or perhaps ever…)
The emulator works by using the similarity between the Z80 and the Game Boy CPU (which is a reduced and slightly modified Z80) in a clever way. I’ll write more about the details in a future post.
