I'm playing 3-player Lost Vikings on Genesis. I read online that, in the SNES version, you can "give" the camera to somebody else by pressing L+R. I tried X+Z (both switch-player buttons) but it doesn't seem to work. Am I missing something?
To switch Vikings on the Genesis:
3 button controller:
Start + D-Pad Left or Right
6 button controller:
X or Z
I personally have always had the three button controllers. I found this article for assistance on the controls for The Lost Vikings on Genesis.
On an unrelated note, this is one of the best childhood memories for me.
Edit: I was misunderstanding that you were doing the three player extension. In this case to switch between players you have to use:
A + B + C
This will cause undesired actions to happen, I don't know if this was overlooked when the game was published for the Genesis or not.
