I used to get the same problem. Sometimes it's just due to what mode the chip is in. I have to do a double reset on my messiah modded ps2 to get ps1 backups to load and as far as I knew a double reset turns the chip off??? try loading the ps1 backup using no resets, then one reset and then a double reset. One of them should work. There are quite a few ps1 games that when backed up dont work. I got Tomb raider 3 original which works okay on ps2 but backup won't work. The backup works fine on a ps1 though which makes it even more confusing. You can get a lot of ps1 games that don't work normally to work by using the bonus ps1 codes disc that you get with action replay 2. Boot the codes disk up, select start game on any game, select without codes then swap the cd's. Theres no need to time when you press controller button. This seems to work well especially on home brew/compilation ps1 cd's.

Out of the 300 odd ps1 games i have theres only two i can;t get to work. Tomb raider 3 and a home brew compilation called ten in one.

Good luck...................Regards
