"[PEGASUS] Added decryption of bios and carts, if first byte is 02. Added notes. Removed commented-out printer."

This sounds.. ugly? Isn't this where you'd want the software lists, and a 'type' to indicate that they're encrypted.

Guessing if something is encrypted from a byte in a cart is a hack at best, and as bad as the 'guess the SRAM size' type hacks that hopefully the software lists will abolish completely.
