Need help fixing my supergun

I have had this for about 5 years now, I got it around 2002, When I first got it it was in good shape, now it's just sitting here collecting dust. It has all the parts, like jamma converter, output to tv, but the wires are loose, and when it comes to this sort of stuff I am not that handy with it. Who can fix this machine for me, I will post pictures of it and how the inside looks later tonight or tommorrow, thans.

post some pics and what the issues are with it. I have built a few super guns I could help you out here.
