Release notes:

[=>] Merged from Dev branch:

Rev 347 – Corn
[+] added ROM setting to enable Body Harvest and Night Creatures to boot
[!] modified IRQs
[+] added roms.ini for GEX3, Donald Duck and Rayman2
Rev 348 – Salvy
[!] Simplified and optimized TLB refill/invalid exceptions
[~] Simplified CopUnusuable exceptions
Rev 349 – Salvy
[-] Removed experimental interrupts (was pretty much a test anyways)
[~] Simplified abit UseIRQmode check, and added comments
[!] By mistake I removed to clear pi status reg in DMA_PI_CopyFromRDRAM…fixed
Rev 350 – Corn
[!] Improved speed in PIF CRC calculations (w/o using table)
[!] Proper name to IRQ hack -> SkipPifIRQ
Rev 351 – Salvy
[!] Clean up options etc (Removed option to disable Stack Optimization, it works perfectly fine with all the games, there’s no point to disable it)
Rev 352 – Corn
[~] Keep texture in the cache a little longer to avoid swapping textures in and out
Rev 353 – Salvy
[!] Add back hack for Aydin, since the assumption I took was breaking Rampage
Rev 354 – Salvy
[!] Enable callbacks when gprof build is compiled
[!] Unlocked volatile memory (this unlocks 4mbs extra of memory) (credits to JJS)
[!] Disabled suspend mode (this won’t work anymore when volatile memory is unlocked) (credits to JJS)

Note: The only side effects when volatile memory is used is that suspend and dialogs won’t work I won’t affect us though, since we don’t depend on neither 😉
Note2: This is pretty much a test, only cheat codes are allocated in volatile mem atm.

Rev 355 – Salvy
[!] Forgot VolatileMemPSP.cpp

[!] Simplified inits of our modules
