[!] Fixed the joystick bug
778
[=>] Merged from Dev branch:
Rev 757 - Salvy
[+] Use a jump table for ConvertImage
Rev 758 - Corn
[!] Use jump table to select native textures
Rev 759 - Salvy
[!] Optimized VI read/write
[!] Fixed a bug in PI write
Rev 760 - Salvy
[!] Implemented osAiSetNextBuffer correctly (optimized it too)
[!] Allocate 8 bytes of memory to handle SP_PC_REG and SP_IBITS_REG (so we can use the pointer table opt and fix some bugs in OSHLE when setting pc)
[~] Removed nasty hack from osAiGetLength (no longer required since osAiSetNextBuffer is implemented correctly)
Rev 761 - Salvy
[!] Optimized OS_HLE_osCreateMesgQueue (we now cache the base address)
[!] Free up 8k bytes from MEM_UNUSED region (dunno why we were using this excess of memory..)
Rev 762 - Salvy
[!] Optimized osSpTaskStartGo (HLE tasks will be loaded directly now when using OSHLE)
[!] Fixed a bug in osSpTaskLoad when setting the status reg, also optimized it to DMA directly
[+] Enabled osSpTaskYield/osSpTaskYielded (I noticed it was used in OOT)
[!] increased MEM_UNUSED alloc to store word size data
Rev 763 - Salvy
[!] Use vfpu memcpy for osSpTaskLoad (since copy is always 64 bytes, we gain from the the VFPU)
