Well I had my slimline ps2 modded by someone. He put a matrix infinity chip inside and I think it is running the 1.36 firmware. Anyway it runs beautifully however I wanted a game of ATHENS 2004 tonight and it wouldn't play (This was an original factory pressed disc!)...I searched Google and found the 1.38 firmware should solve the problem. I have now just seen a beta 1.4 firmware is out, and this will enable me to back up Gran Turismo 4 onto a DVD+R Dual Layer disc and play that. Now I am a total n00b for chips - is it easy to update the firmware myself and has anybody tried GT4 on a DVD+R DL yet Thank you!
