Hlide here again.

You probably read an old post where I stated some games might randomly freeze when vsync limiter is ON. I must admit I was completely unmotivated and didn't make any progress until I decided to get back to pcsp development today and finally pinpointed what I think to be the cause. Vsync thread uses a timer to emulate a vsync event at 60 Hz. But the timer (windows has a 32-bit timer) handled uncorrectly a 32-bit overflow. Superfruit game was always exhibiting this issue when this overflow occured. Superfruit game now plays fine with vsync limiter ON.

As a result, a minor version may be released soon - or a major version if EBOOT decryption is added in the month.
