I'd like to say that I remembered what was going on here, but I'm not certain. I think this allowed you to pop in different carts and have characters from different games play the...

I'm pretty sure I read that somewhere.
Anyways, I'm pretty sure I'm not confusing that with the MSX2 which did have some glitches possible when you hot-swapped different Konami game carts or what have you.
