Play backups via AR carts?

CD-ROM Backdoor

The CD-ROM control chip in some PlayStation models supports a debug command to disable most of the disc authentication. However, this command would have to be sent from the PlayStation itself (or modchip), presenting a chicken-and-egg problem for those who would use it to play copied discs. Additionally, these commands don't disable all authentication, so a game would still be able to detect the use of a copy.

The protection can be disabled by sending the correct command sequence to the disc drive:
Couldn't an PIO AR/etc do this at start up for 2mins then auto stop.. it would make it undetectable.
How would it run in the background tho? hmm
