like the title suggest, I'm looking for a phat PS2 mostly for the possibility of installing an HDD and never have to burn a single dvd. my question is that I want to know if the modchip installed on the console has some importance on the HDloader or not. my other point is that I also want to run PSone games, I already know that is impossible to load PSone games through HDloader or USB loader, so my question is, what modchip support load PSone backups via disc??. as far as I know some Matrix Infinity clones fail to load PSone backups. I can buy a PS2 phat with(apparently) an original Matrix Infinity or a virgin PS2 phat and install a modbo 4.0. the virgin option is tempting because the laser is at mint condition for obvious reasons, I'm aware that the modbo is a Matrix clone, but if HDloader and PSone backups works well I'll be happy with that.
