TOC is game disk larger than the backup you want to play.
Put a DVD game disc in your PC and check it's size in GB, like say GTAVC is 4.34 GB (Large)
Boot Cogswap then insert GTAVC or whatever large disc you have.
Cogswap reads it, the Cog disc turns yellow and it reads PS2 DVD.
Press X, the disc turns purple. Insert your backup.
Enjoy!
TIP: You SHOULD use FMBC, it's a lot easier and there is no need to swap discs
Yes the memory card exploit you are trying to do only works with fat ps2's. FreeMCBoot is a way to boot elfs without a trigger disc or another kind of mod. You can use this on your slim but you have to read up on it and see how to get it to your MC.
K, I think I know how to get it there I just have to read up on it.
Correct me if I'm wrong again lol:
you put it on a flash drive take it to your PS2 and with code breaker I can copy it to my MC with the device manager in code breaker. I'll read up on it now, thanks for all the help.
