LLEs

I think these work when LLE'd

cellCamera
cellJpgDec
cellGifDec
cellSre
cellSpursJq
cellFiber
L10N
libgem
libvdec
libavcdec
cellSail
cellSailAvi

I haven't tested the others properly

cellCamera and libgem definitely aren't going to behave as they do on a PS3 - they're unable to actually interface with a camera. Almost all hardware facing modules (ie. cellGcm, cellAudio, cellVideoOut, cellSysconf, cellMsgDialog, cellNetCtl, etc) aren't going to work or are going to simply not have the same output.

I think there are some games where LLEing cellCamera helps getting further in the game's emulation, but it doesn't work as intended, same for libgem
