Remove a bunch of freshly-obsolete code
Implemented missing lswx and stswx instructions. Tested with Wii PES 2008 (PAL), which now works (OpenGL devs please take a look at this game).
Changed the scope of some variables introduced in my previous commit (r6132).
IR pointer rotation finally working… Added a low-pass filter over sin and cos, but I still get some jittering… I suspect it’s the numeric values… Billiard? Can you please help me on this?
