Pro Evoulution Soccer 2 & Ps-x-change V2

[popmart2k1]

I have downloaded a backup of the KONAMI P.E.S 2 (Pal). I have burned into a cd-r and i´ve tested the game in EPSXE emulator from PC. The game works 100%. But when i try to play the game in my PSONE, using the boot disc PS-XCHANGE V.2, the game no works. I´ve searched protection codes, with no results.
What its the problem??? Anyone can help me??
Thanx.
