I actually asked that 4 or 8 way question the other day in the Arcade Cab section of the forum. I bought 2 switchable 4/8 ways & I like them. they are the Mag-Stik Plus from Ultimarc. I may throw the 2nd stick down at the end...just so I can play RoboTron. I am just looking for any suggestions on good games I'll be missing out on without having a 2nd player. It seems everybody is building a 2 player console.
