What's funny about this is that Sony eventually corrected one of these flaws at the expense of the other - the later-model "Slimline" PS2 came built with an Ethernet port, but was completely incompatible with the PS2 hard drive.
The game, as originally presented by Capcom to the gaming press, was supposed to be comprised of twenty scenarios. It actually launched with five, with File #2 offering five more.
Data for File #3 is on the File #2 disc, and can be accessed with a Game Shark. This mostly consists of a number of additional playable NPCs, which includes HUNK, a couple of members of his strike team, and a plumber dressed like David.
