EDIT: And I've gotten myself a Japanese Model 2 controller from a trusted source. Still haven't picked up AV cables yet.
EDIT2: I've found some AV cables too. Now I just feel bad about posting all of this in the first place, but I guess it'd be nice to know where to look for a second controller in the future.
I'm looking for games like Sonic Jam (which seems impossible to find), Mega Man 8, Rayman, Sonic 3D Blast, Capcom fighters, and (if they weren't so expensive) the Panzer Dragoon games. Complete, NTSC-U versions to be exact. There doesn't seem to be many NTSC-U games on eBay so I'm wondering if there's some shop online I somehow haven't found that sells them? Are there any hidden gems I should look into getting?
