The neo2.2 is one of the first generation of modchips that came out for the ps2.

Many of the first generation modchips required you to swap discs without the ps2 knowing in order to play backups and different region games.

With the neo2.2 it was generally the Action Replay and Gameshark that was needed, you'd load that, then put a high content dvd in (Like GTA3), do the sequence above changing the disc while the drive was out. Meanwhile the ps2 doesn't have a clue.

I posted the sequence for you in case u wanted to make 100% certain of the install. Another way of testing is that ps2 CD based backups will boot like the originals. The swap was only needed for dvd based games.

The sooner you get that thing outta there the better but I would warn you that it deteriorates the laser even without doing the technique etc above.
