MGS2 won't boot.

[Beefcake]

I chipped my v5 ps2 with a solderless chip, and I'm unable to play a backup of Metal Gear Solid 2. I'm pretty damn sure the burn is good as I can see all the files on the disc when I put it into my computer. I used primoDVD to burn it and the burner is a Pioneer 104 (A04). I've tried 2 different methods to swap it, but neither work. I tried swapping the disc out as per the instructions that came with the chip, and I also tried changing codes and the swapping while it updated the code list. Any other ideas (besides getting a new chip, unless someone's willing to cut me a deal on installation)

Thanks
