op for the everything, get the wii one its $40 and has 8 buttons, and is still hori, grab your PS1 controller and mod its motherboard in instead, buy your pelican adapter, and tada for like $40-60 bucks depending on what you have.
Ends up being compatable with
Wii (GGAC, lol)
Xbox 360 (Virtual fighter 5, and some other 3d's)
PC (critical)
PS 1-3 (critical)
