Strangely enough, the game still runs without any adverse effects in my cd-burner. However, when I tried to run another SD2 game, it bombed out with a message to eject and re-insert the disc (standard error for a failed ATIP check, NOT the usual “insert correct CDROM one”). Sure enough, the “ignore media” type box was cleared. I ticked it back on, and it worked fine until I ran the game again. Then it got cleared again.
Is anyone having a similar issue?
