PCSP v0.4.0 - vsync limiter on may freeze some games
Hlide here again !
Ok, Evangelion doesn´t run anymore. I guess the addition of Audio and the changes in threadman are probably for something. In fact, I suspect some games were able to run in a very hacky way because the thread scheduler wasn´t playing its role properly and so some waiting threads were awaked even if their waiting condition wasn´t met. And it could also explain why this game was so slow.
A new vsync limiter was coded using a time critical thread to wakeup any psp threads waiting for a VSYNC event. It is a cleaner way to limit FPS to 60. A change in threadman was necessary to make it work.
An audio implementation based on PortAudio with its own time critical threads to play audio samples also needed a change in threadman.
As a result, you may really need a multi-core to keep a smooth running pcsp.
Beware, this version is very experimental : if you have some games which ran fine and have a freeze ingame with this release, try to disable vsync limiter and relaunch pcsp to check if it occurs again. There are probably issues with inter-thread synchronisations and they are very hard to spot. A new minor release will be out as soon as a fix is found.
