US-PS2 with Modchip and gameshark2 cd-1 as boot still problems. Please help getting pi$$ed off

[Babar]

I have a PS2 with modchip installed and bought the Gameshark2 cd-1 to use as a boot disc for my US PS2. I copy games using CDRwin to my harddrive, then get the patch and apply it using PPFomatic, then burn it back to a CD-RW (RW so I can erase and try again) using CDRwin at 1X speed, but when I try to use the disc using the swaptrick it never loads the game. What am I doing wrong. I have tried with PS1 and PS2 games but no luck.
Please help!!!!
