VGS it's an old, hacked, discontinued & (once) commercial emulator which has problems with XP as hasn't been updated since ages (and won't ever be because Sony bought it). Better stick to ePSXe, PSXEven & SSSPSX

CVGS can't be played on Windows XP. Even with the hacked version (Emurayden) in which pec couldn't recognize it.

Pec only works exclusive on ePSXe and CVGS only. So, try to stick on ePSXe if your PC is WinXP.
