im honestly using 1.4 the most, with Configurble right behind it, but i dont really need to load into a different language or video mode that often. i do enjoy the occaisonal Ocarina cheat though.
and once the libwiigui version is fixed up (and its source cleaned up, so many people worked on it, it must look a mess), i'll probably use that hands down, barring any instability or game crashes it causes.
