It's the year 2009, and it's almost over at that; and as anyone reading this blog well knows, multithreaded applications are the here-and-now and future of desktop computing. It's the only way we can take advantage of multicore CPUs. But multithreaded programming offers more than just improved multicore performance. Using threaded programming is actually very important to developing software that behaves nicely . By that I mean software that refreshes its window contents quickly, responds to your mouse clicks, and lets you cancel stuff.

As of Sept 30th , we've re-enabled user comments at our SVN repository PCSX2 @ Googlecode.

From 0.9.5 onward PCSX2 has been a mostly open SVN revisioning process, where beta builds are SVN-marked and are widely built and distributed to users. 0.9.5 itself was never released as an official 'stable' build, and after the release of 0.9.6 we just called all subsequent SVN builds of PCSX2 "betas." (mostly because we were too lazy and/or busy to bother worrying of version numbers). This lackadaisical version pattern was a source of confusion for users and developers alike.

This begins a series of blog posts intended for ps2 developers and ps2 emu authors. Its purpose is to give some light to some of the secrets I've learned about the VUs while developing my mVU recompilers, and to describe what happens in situations that are a bit questionable.

In pcsx2's advanced options dialog (if you've dared to look), you've might have noticed there's "FPU Clamp Mode" and "VU Clamp Mode" settings. You may even have experimented with some of these modes and found out they fix or break games. But what are they doing? And why so many options?

One of the first things I sought to do when I first started contributing to PCSX2 was to improve the emulator's overall stability and error handling; and to this day it's still one of my top priorities.

If you'd like to make comments or ask questions in response to a devblog entry you can now do so from the PCSX2 Public Forums . Yes, unlike some frivolous free-for-all blog with a thousand disgusting comment spams, our DevBlog requires that you must be a registered user and logged in to post.

As most of you know we use Google Code for our Public SVN repository, and doing so has its pros and cons.

One of the major changes planned for the next release of PCSX2 is a complete overhaul of the gui/frontend, switching from the current "native" Windows/Linux interfaces to a single unified interface that's (more or less) the same for both platforms. To make such a grand vision possible we needed the help of a third party gui tooolkit, from which there were several to choose from. After much consideration we settled on wxWidgets , which is the same toolkit used by a few other notable emulators, such as Dolphin .

While not likely to win the prize of being featured in PCSX2's next release (presumably 0.9.7, but you can never be too sure), this logo might deserve honorable mention. I present for you a moment of Zen:
