mod chip boot help. PLEASE

[premierx]

I bought a ps2 already modded. the problem is that it wont play some games ( 007 agent under fire, fifa 2002, dynasty warriors 3) and a few others. all these games work on my friends ps2 so there is nothing wrong with the games. i believe i have a no-solder mod. i have tried about 100 games of which about 80 work. is there another way to boot them up? currently i just hold eject until the light on reset changes and swap disks. please help - as this is doing my head in

I have tried burning the games on different disks (74/80/silver cdr/ purple cdr) but nothing works. they seem to start loading but the screen just stays black.

the other games are f1 2001, batman, onimusha, splashdown, wipeout fusion, gt3, zone of enders & summoner. do I need patches? if so how do you do it? and where do you get them?
thanx.
