I've hinted at it so much there's no point in keeping it under wraps any longer. For the longest time, I've been working on a way to port GB games to the GBA. What I ended up building is a modified GB to GBA emulator that targets a fantasy console instead - I call it the GB Bridge.

GB Bridge is basically a GBC with a different memory map, a bigger screen, and extra inputs. The real trick is that I use special registers to trigger native GBA routines from the emulator - meaning that, while very hard to pull off, I can push things as much as I want.

What registers in particular if you don't mind me asking?

It's tentative, but for now I'm using $FF58 and $FF59 for GBA events and $FF5A for JOYP2.

What I've posted are mockups of the end goal, but I've tested key parts and they are feasible. I'm currently working on SML. Like most of my stuff this is long-term, so please don't expect releases anytime soon. That said, I hope I gave you something cool to look forward to.
