2 player cocktail games?

[mogse]

hi
i have built a cocktail machine with a player control on each side,
the monitor is vertical
i was just wondering if anyone can recommend an arcade game for mame that can play two players at the same time?
like pong,soccer,tennis etc..?
any suggestions would be appreciated

I love Hat Trick.

The player controls will need to be mapped differently for this game since it wasn't designed to be head to head like that but it works great once you've figured it out.
