It's really up to you to see whether or not it works. Report back if there are any problems. And btw, as for media, yours should be somewhat fine but if you can, a DVD-R would be nicer for the older fat PS2s unless you've tried those already and possibly the 8x disc or lower depending on your preference. If you want to stick to the media you are currently using, it's up to you but if you want better results if the one you are using goes bad somewhere in the middle of the game, try switching over to some Ridek (Ritek?), Verbatim, or Taiyo yuden blank media to spruce up your chances for success better. As far as it goes to working, try it and see then report back.
Ok i got a DVD-R now and imma try to burn it. Also i want to Swapmagicfix.com and they said something about a CDLoader but imma ignore that. But before i'll burn ill try to fix online play.
I don't think you can go online unless you apply a Toxic patch or something to your ISO to get through Sony's online checking system. As to how to apply this, I never done so before. Good luck finding out about it because I never really went online to play except for 2K6 this one time. And as for the cdloader, I think those are for old swap magic versions, but I'm not quite sure either.
