Cd-r backups and GS help

[brkr101]

I have an RMod along with swap magic discs. I have quite a few backup cd games and dvd rips that won't work. After reading in the forums I found out that some games don't work with the swap magic disc. I also have a GS which I believe is version 1.92 and tried to do what the post by Nightstalker stated but doesn't work for me. After I select "start game" and "without codes", I press and hold the eject button until the light turns orange, I switch the discs and it closes automatically. Then I press "x" and I get a red screen that tells me to insert a PS2 game. Could this be b/c my GS is too old? Or is it b/c of the RMod? Or is b/c I'm a moron and am doing it wrong??? PLEASE HELP, I'm an idiot but I'm determined to make this work
