ps2 with messiah 2 chip.

[vvolf119]

I bought a ps2 with the messiah 2 mod chip. I have burned madden 2004 onto cd and socom navy seals onto cd. The game will start and let you play it for about 5 minutes but then it freezes up. I have been told this could be a copy protection. if so how can you fix this problem or is there a patch to download. I havent seen any patch for madden 2004 any help would be greatly appreciated.
