I was looking around the games I got off GameStop's PS1 clearance sale, and I noticed two of my games support Guncon and Justifier guns.

I was wondering, will the Guncon 2 work with Guncon 1 games? And if not, can I use Guncon 1s on slimline PS2s? I ask because one of the games I got was Gunfighter: The Legend of Jesse James, and it is FANTASTIC. Imagine Time Crisis... in the wild west.

I remember seeing a gun that had a Guncon 1 and 2 switch at the flea market, but I couldn't get it because all the cables were tangled up...

Edit:
Doh. I have no clue if the PS2 is considered "classic", so feel free to move this if you want, mods.
