HDD Codes and Modchips

[cbflip2000]

the answer is false, there is no special code. i tried using my PS2 HDD with my brothers PS2 and it worked fine. It even plays back ups on a un-modded PS2 as long as you install the game to the HDD using a modded PS2 and using the HDloader disk.

Oh yea, i know it is illegal to make more than one back up of a game, but can i put time crisis 3 into the hard drive with 1 PS2 and the original disk on another PS2 to play 2 player LAN mode?
