After a brief period of slowed development, PCSX2 has started picking up
speed again with the help of new contributors as well as familiar faces.
Several important improvements have been made since the last announcement.
The most important of these improvements is undoubtedly the new debugger. Our
debugger has long been an area in need of attention, and thanks to Kingcom it
has finally received a much needed overhaul. This new debugger will make it
much easier to chase down the problems in broken games. Rama has already
managed to get the NHL series working by using it! Featuring a live
instruction assembler, thread view, full register view, a function list and
more, this improved debugger will certainly be a boon for our developers.
Another area that has received welcome attention is work towards 64 bit
compatibility. Although there is still a lot of work to be done before we
release a 64 bit build, the foundation has been laid. GSdx compiles for x64
now, and several key changes have been made to the PCSX2 core to support x64
as well. These changes include preparing the emitter for 64 bit jumps,
updating vtlb to work on x64, and changing instances of 32bit only code to be
universal. These improvements help move us closer to having a true 64 bit
build.
Linux matters have improved as well. Many of the new contributors use that OS
instead of Windows and improvements here always help general portability in
the long run.
Lastly, a few important changes have been made to some of the plugins. On top
of general bug fixes, CDVDgigaherz now tries to keep the disc always spinning
at a low speed instead of letting the drive spin all the way down. This
improves game performance when using a physical disc because the drive is
always ready to provide data. Lilypad also supports hot-plugging of Xinput
devices now. That means if you forget to plug in your Xinput device before
starting PCSX2, it will recognize it when it is plugged in without requiring
a restart.
Here is a rundown of the most significant changes:
64 bit related:
- Changed instances of u32 to uptr
- Prepared emitter for 64 bit jumps
- Made yuv2rgb and hashmap functions 64 bit ready
- vtlb now works on on x64
- Supported grabbing the MXCSR mask on x86_64 in cpudetect
- GSdx now compiles for x64
VIF:
- Fixed “Looney Tunes: Back in Action”
Improved Debugger:
- Allows much easier debugging of broken games
- Already used to get “NHL” games working
- Features a live assembler (e.g. mark an instruction, type “nop” to replace
that instruction with “nop”)
Plugins:
- Bug fixes for CDVDgigaherz
- CDVDgigaherz now prevents the drive from spinning all the way down which
improves performance when playing from disc
- Lilypad supports hot-plugging of Xinput devices
Code cleanup:
- Changed int to bool for variables that only hold 0/1
- Fixes for potential crashes
- Fixes for potential variable leaks
- Preparation for WX3 (for now we still use a custom 2.8)
- Removed managed Vsync
- Folder name fixes for Windows/Linux
- Improved use of namespaces
- Fixes for ELF parser
- Started using generic memcpy instead of custom one(this actually brings a
small speedup!)
Misc:
- Updated translations for several languages

看來是趨勢吧...

有加速效果嗎?

對PCSX2最消秏資源的SSE2暫存器效率,應該會有一些影響不過 除非有人接手並大幅最佳化cottonvibes跟Jake 那些與GS 及microVU 相關的上千條code (ex:MTVU&MicroVU)否則個人推測 應該是看不到什麼飛躍性的成長就是...
