Interesting, I had heard about a "Daum Branch" but I didn't know the main trunk was that active.
As a completely irrelevant trivia, if you play games on DosBOX, try and use them with Munt (Roland MT32 emulator) if they support Roland MIDI. I am currently playing Police Quest 1 (VGA) and it sounds amazing.
Reminds me of the Gameboy Advance emulation scene and the mess that was VBA - eventually mainline was abandoned, VBA-m seems to be the maintained fork, but there's also VBA-rr.
Thankfully, us linux users have a good gba emulator now. Windows already had the legendary no$gba.
And what about the PS emu scene? PCSX is dead, so your choice is between PCSXr, and ePSXe. There are meaningful differences between the two, but it's pretty hard to know that up front.
The DC emu scene is almost nonexistant, all the emulators have been abandoned, none of them work on Linux (Reicast claims to, but it doesn't: I've tried), and even on windows, most games barely run, if at all.
And then there's the NES emulation scene on GBA: pocketnes is the best emulator by far (it's amazing), and you can find copies floating around, but you need a pocketnes rom maker to build the roms, and that's hard to find, especially on unix. The only one I've found for unix is mkrom, and good luck getting your hands on it: I had to trawl archive.org for hours to find a copy.
