PPSSPP for Windows XP

[GuilhermeGS2]

The main informations I can't identify: processor and graphic card. Probably it's an old onboard, because your PC is old (G31 chipset) like mine. But the problem with DBZ is more probable to be a compatibility issue with Direct3D backend or even any emulator feature than a hardware issue. Check out the the Compatibility forums to know if the game is actually playable.
