Which PS2 games use the firewire connection?

[Purkeynator]

I have an old school launch PS2 that has the i-400 firewire cable port on the front. I know that you could link certain games with it and play multiple PS2's on multiple TVs. I know that Gran Turismo 3 and Timeplitters 2 use the Firewire connection. Are there any other games that use this connection? Also has the ethernet port replaced this as the way to connect multiple consoles to eachother?

Armored Core does.

Anybody else know about this?

I could use this info as well, since I have one of those third-party iLink cables.

Wasn't there some kind of chart on the official playstation website that lists accessory compatibility or something like that?
