Dungeons and dragons shadow over mystara

[markedgar]

I am able to enable 4 players in mame 2010 by opening the game and changing the configuration to 4 player multi chute but now players 3 and 4 are unable to use magic. Has anyone encountered this problem? Any solutions?

@markedgar Sorry, I have no way to test this situation, but searching the forum I found an old post from another user reporting this problem, unfortunately there is no report of a solution:
