I did way back when it first came out but now no,no i dont.

Its hard to get back into that version when you are so used to much better ones by now.But if that was the only way i could play mk1 i would.I kinda miss playing as goro in that version since it was the only one that would let you.But even back then I'd give it about a 4 out of 10.

I've played it on the Game Gear, but not the Gameboy. Other than the obvious, is there any differences between the two versions?

yeh i think mk1 on gameboy doesnt have johnny cage on it

its sick yo
