Mortal Kombat on the GO! is ALMOST a no GO! because on some problems with both 2 & 3.
The only problems are in the MK 2 & 3 games. Some levels don't have stuff in the backgrounds and the sound effects are higher then the music(which SUCKS). In MK3 when you pick Kabal is doesn't say "KABAL", but hey its MK on the GO! which really overshadows the problems but not by much.
The other games are Spy Hunter, Sinistar, Paperboy, 720', Spyhunter, Klax, Joust, Marble Madness, Gauntlet, Toobin', Rampage, Xenophobe, Wizard of Wor, Championship Sprint, Arch Rivals, Cyberball 2072.
