No Solder Mod Swap Trick
 

OK last question I promise. The No Solder Modchip. I know it can play DVD-R's with an original DVD game which has a higher TOC than the copy. Now can you boot Cd'rs over 650 mbs with a DVD game? Or can you boot the Cdr with a CD rom based game that has a higher TOC than the copy? Please help....

Definitely not. The PS2 thinks it's got a DVD and expects to continue with a DVD.
