PCSX2 beta 831 - PS2 Emulator for WIndows

March 23rd, 2009, 19:00 Posted By: wraggster

New beta version of Sony Playstation 2 emulator for Windows has been released.

Changes:

- Major overhaul of the savestate system! SHould now work better, be faster, have fewer problems, and use less hard disk space for the savestates
- The new PCR/TIMR code is now called correctly in recMFC0. This fixes Fatal Frame, maybe other recently introduced problems too
- Improved CDVD seek timing; should speed up some games that had abnormally long load times -- hopefully without breaking other games. (testing needed)
- Fixed a condition in the INTC hack that could cause it to hang in rare
occasions.
- Fixed a bug in the vtlb constprop support (stores weren't using the right macro)
- More work on fpu (thanks Nneeve)
- Emitter: encode negative 8 bit immediates for some instructions and EAX forms for MOV
- Implemented more correct support for the IOP's "isc bit" (bit 16 on the COP0 status register), which in turn allowed me to simpify some of the IOP's memory access and paging logic.
- Removed unnecessary rs flushes for loads and stores
- Save a few bytes on const flushing using 5 byte eax movs for 0 and -1 instead of 10 byte immediate movs.
- Usual code cleanups and optimizations
