did you guys start working on the GBA emu or did you start from scratch?
There's only one developer here. If Nukefall throws me what he's done with the config, there'll be an official contribution, but I'll still be the dev

I started with emulating the GBA, but the code is (most)all my own work; you could say I started on this from scratch. If you grab old versions of DSemu, you'll note they can only open GBA demos. Even now, I have more screenshots of GBA stuff running than I do for DS, and this situation will remain for a while.
