I'm not sure if I completely understand your question, but if you're trying to record a PS2 game with CDRWIN all you do is:
-> Click on "Record" button
-> Click "Load Cuesheet"
-> Select the backup copy of the game that you copied to your hardrive (ends with .cue)
-> Click "Start Recording"
It doesn't get any easier than that. Oh yeah, make sure you put a blank CD in your recorder...for some strange reason you need one of those to burn a copy.
If only someone would answer my post...
