hate to say it but you will have these problems with the swap magic disks you will have to get a real mod chip installed, (one that will have to be soldered inside the ps2 )as these disks will become useless as some of the new games have a double toc check that will stop them loading as the games size wont mach the swap disk.
sorry i could not be more help to you but a real mod chip is the way to go
