Work towards PCSX2 0.9.4 continues at a steady pace! GiGaHeRz has done significant work towards USB emulation, and we now have keyboard support!

Since 0.9.2's release, many users, mainly those who live in Brazil, have had problems running the VM version of PCSX2. After trialing this fix on the forum for the past 6 or so months, I figured it was about time we put it on the site!

In our spare time, some of us do little things to amuse ourselves and others, generally involving the betatesters, the devs, or generally people who come in the IRC channel.

Since its summer time and nothing much goes on these days (yes the devs and testers also have lives!) I thought I'd entertain you with some videos I recorded, showing off some of the new fixes in 0.9.4.

It was apparent early on the project that the GS plugin was going to be a big bottleneck during 3D scenes. It isn't that the GS plugin itself does a lot of computation on the CPU, but the fact that it needs to communicate with the graphics card means that unnecessary stalls will occur in the graphics driver as the GPU and CPU are synchronized. During these stalls, the CPU basically goes to lunch until the GPU is ready. Graphics drivers and libraries are aware of this and try as little as possible to communicate with the graphics card. They usually cache render state changes, shader changes, and texture changes up until actual geometry is rendered. They also take advantage of FIFOs (first in first out buffers). The CPU just writes to the FIFO and the GPU just reads from it, this makes all the difference in terms of keeping the GPU active while the CPU isn't and vise versa.

Okay, they aren't new, they have been on NGemu a while, but they have been getting some good support from the community and i felt they needed adding to the official site!!

Recently PCSX2 has made its second appearance in the Italian magazine - The Games Machine . It's great to see PCSX2 getting mention in publications, and we thought we'd share the article with you!

Florin has just released BIOS Dumper v2.0

Testing can be a comical affair!

Refraction, what have you done? You've changed history. You've created a Time Paradox!
