I enjoyed,
Virtual Racing Deluxe
Virtual Fighter
Star Wars Arcade
Space Harrier
After Burner
Shadow Squadron
MetalHead (some people liked it at the time, some didn't) you control a giant mech first person
Motocross Championship (dirt bike racing)
BC Racers (loads of fun with Chuck Rock characters in a Mario kart type racing)
Tempo (platformer)
Zaxxon Motherbase 2000
I have a few other games but these were the ones that stand out to me. I think I am going to have to get that thing out and hook it up again. :-\
Hope you get all the cords and hook ups.
