The legendary #Workboy found a new home! I ported the ROM to work on the #MegaDuck laptop (a #GameBoy clone). Not the hardware we wanted, but...it's hardware that exists! Keyboard, Real Time Clock and all. Free #DuckDuckWorkboy #rompatch on the itch page: bbbbbr.itch.io/mega-duck-pa... #romhacking

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!

I used my game boy camera to take a photo of Jupiter using the Mount Wilson 60 inch telescope. Literally, it discovered the Milky Way, and now I use it to take the lowest resolution astrophotography ever. Full process video here: youtube.com/shorts/cS0Mu...

alright i've put up this GBA ROM, for ArduinoBoy live MIDI input, and (if you've got an EZ Flash Omega, or EverDrive X5 flashcart) playing MIDIs off the SD card since you can't rly edit/provide soundbanks yet, it's just a GM-compatible MIDI device with a very limited (and kinda goofy) soundbank lol

more GBA midi stuff, this time sending a more substantial amount of data over the wire lots of electrical noise unfortunately! not sure whether the GBA amp upgrade i plan to install will help with that at all. (featuring some more old anime MIDIs.. Mai Otome this time)
We have a fork of agbplay that lets you open any GBA ROM that uses the MP2k driver ( see list of games with their driver here gist.github.com/loveemu/60e2... ) and route any MIDI input to it and play it like a MIDI synth We've used it for composing for MP2k games Would anyone else find it useful?
