Oops, , I thought I'd mentioned it before, but yeah, I've ported snes9x-1.43 to the ps2. It's already compiled, but I've gotta implement the basic port functions, as well as things like graphics/sound/input. Then I just need to plug-in the file browser and create some custom menus.
I'd tried to port snes9x-1.51, but for some reason, libstdc++'s <string> library wasn't working correctly for me, and the updated internal input emulation is dependent on it. It compiled fine without the internal input functions though.
