PCSX2 development picks up speed

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

PCSX2 drops AVG Toolbar

This news post comes at an awkward moment, but AVG sent a letter a while ago stating they were terminating our partnership, and this termination has now become effective. Because of that, we have uploaded an unbundled version of the latest release installer, which you can find in our downloads section.

We would like to thank those users who have provided us with donations and supported us through our bundled toolbar. They have been essential in ensuring the team can afford the things required to improve the emulator and keep everything up and running.


Thank you all for the support so far!

Config Guide 1.2.1, updated netplay plugin, updated compatibility list

I finally got around updated the configuration guide for the 1.2.1 release with all the new features and also adding some new plugins that most people don't know about Smile You can check it out here as usual and you can find instructions on translating it to your language here.

I have also updated our netplay plugin DEV9giga-razi to include the latest fixes brought by two contributors in Git, MrColdbird and Bigpet whom we thank for their nice contributions. The plugin should crash much rarer than it did before, so we hope it will be usable for those who couldn't run it. You can get it at our windows plugins download section.

Finally, thanks to a lot of contributions from forum members (DESTRUIDOR,JBoughter,Altomar and many others), our compatibility list has been updated and expanded, so take a look to check if your game is working in the latest PCSX2 version and nice settings for it to get around its problems.

PCSX2 source code development switches to Git

Hey everyone,

We just moved the PCSX2 version control system from SVN over to GIT.
The new official source code repository is hosted on GitHub.
You can find the source code here.
And the new issue tracker here.

Git is more contributor friendly than SVN. The process of sending patches to a team member for eventual review has been streamlined.
Now people can just fork the master repository, add their changes and open a pull request if they think it's good. The devs can then merge the request and the code is live.

This change is a pretty big operation, so please excuse (and report) any issues you find while we're transferring Wink

Keep in mind the build bot will take some time to update to the new source code repository, whenever Orphis can get around to it so until then, be patient!

Linux PCSX2 1.2.2 release
