📄 Description

For #1247.

Turns out that the 512KB PS1 BIOS on PS3 is incompatible with the fast boot patch and seems to get stuck in an invalid bus read/write loop. TTY patch doesn't look like it works either. Disabling patching for it should be fine, since it's effectively a fastboot BIOS anyways.
