Before Naplink was avaialbe the only technique available to test code was to burn a cd and use the AR2 swap method to run the program. You build a CD by doing the following.

1. Create a CD ISO image with
   [file name].elf
   system.cnf (contents described in patcher)
2. Use CD Patcher to patch ISO image.
3. Burn CD Image.
4. Use AR2/GS2 swap technique to run.

Note You can get the CD Patcher from Duke's site, called ps2patcher.zip under files.
