Thanks guys for the comments so far they are actually pretty helpful lol...and yes I was trying to say masterplay interface lololol...also, I meant to say that my controllers were messed up, not my systems.
Anyways I did manage to secure a total of 4 wico controllers with 2 y cables and an keypad for overall an fairly decent price, 2 atari jaguar controllers that are converted to play on the 5200's is on the way, and finally the really cool gentleman by the name of Bohoki replied back to me and sold me an adapter also...oh yeah and I found 2 trackball controllers that work for 50 dollars... I think I'm set lol. I've been playing a few days straight now and i must say that this system has an "red head step child" appeal to me... I love it but it makes me angry sometimes..those controllers and short wires ugh!!!....lol I kid ...I really do think this system and the way the games look and how they are played with an decent controller is totally underrated and should be given more credit.... Grelims, defender, and missle command ftw!!!!
