Because there's just one emulator, dolphin. I'm unaware of any other major ones?
Exactly. The GameCube/Wii emulation scene does not have any of that drama like the N64 scene has, which leads to everyone in the scene being happy to work together on one single emulator instead of everyone working on their own projects.
You can broaden the scope to console hacking in general. Even if drama's your thing, you probably won't last more than a few years.
I wasn't very clear; yeah, exactly! I was talking more about the broader console hacking scene. It's a mess, heh.
