GBE is not active. The 1.0 build is the only stable build compiled at the moment. Development will continue with GBE+ -> https://github.com/shonumi/gbe-plus
The current focus is to get a decent amount of GBA game's running (without sound), and once GBA emulation matures, GBE's old DMG/GBC code can be imported. The goal is to create an emulator capable of playing games from all 3 handheld systems and offer the ability to replace graphics in all of them. I'm going to make a Qt UI for the emulator that will make dumping, loading, and editing the graphics much easier than it currently is. For example, want to dump the background? You have to click on every tile! While the game is running! A proper GUI will make that all go away.
I haven't gotten to it yet, but I plan to abstract key classes within the codebase (Core, CPU, MMU, LCD GamePad, APU) so that whenever GBE+ needs to boot DMG, GBC, or GBA games, it can just create specific instances of each tailored to each system. Hopefully this will smooth things over for the eventual inclusion of DS emulation. Yeah, I know it sounds crazy (a DMG to DS emulator) but byuu managed to do it for a time, and large portions of the DS (particularly the 2D engines) are copy+paste from the GBA, so it isn't a huge leap to take.
