To quote: PlayStation 3 RPCS3 SVN r43 is compiled. rpcs3 is an open source PlayStation 3 (PS3) emulator for the Microsoft Windows. Current versions can run only small homebrew for PS3. Developers are planning to make it to emulate PS3 on its speed in the near future.
Make PS3 developers easily test their apps and homebrews on PC without crashing their PS3 or moving their apps from PC to PS3.
Just playing PS3 games on your PC and have fun! (In the future)
RPCS3 SVN Changelog:
Emulated more PPU / SPU instructions.
Fixed some PPU syscalls.
Fixed issue 4.
RPCS3 WIP - Cube (simple PS3 homebrew testing)

Here is an update from KDSBest (via twitlonger.com/show/l3h9er) on the RPCS3 Emulator, as follows:
I took a deep look at the #RPCS3 emulator especialy the ppu emulation. It is possible to increase the performance alot. Since my time is big money I try to get some PoC stuff out. IMHO the performance can be increased by a multiple times. Starting with the decoder which is nicely writter TBH but not tweaked to the performance limit. Building a big switch case is just the wrong way.
Don't get me wrong they made a nice piece of software, but the lack of performance tweaking makes it a bad emulator. Instead of making things look nice they should focus more on pushing the performance to the limit. Look at Dolphine code it is plain ugly to use, but for the performance sake.
I work on a recompiler, which TBH i never expect to be full featured on my work alone. This is way to much to handle for one person, but it should give #RPCS3 people a well knowledge what can be increased.
First of all I try to show the improvements to the decoder, which will be sick. The thing is this, the decoder does alot of stuff which can be done at load time. Loading at startup is not interesting. The performance while it emulates is crucial.
Second I always said it and I still need to say it again. Building a recompiler is not much harder than emulating the stuff like they do but the performance increase will be insane. I looked alot at recompiler codes lately to get a brief understanding how they work and it is doable for the PS3.
I hope #RPCS3 guys will take my help instead of claiming false that their way is faster and reconstruct their emulator. Of course I want to get credit than, because this will be work not much people on this planet can do.
To the decoder using binary search algorithms is way faster than doing the big switch case.
If I manage to make this work I will try to give a presentation on CCC Congress or other congress that let me show this stuff since IMHO it is technically more interesting than what most of those congresses show.
