Converting Nintendo VS Unisystem to a 2-n-1 arcade game

I decided I wanted my Vs System stand up cabinet to have 2 games instead of 1. It already had Dr Mario, the natural choice to compliment Dr Mario is Tetris. I installed Tetris ROMs on the other half of the Vs System board and installed a Vs Interchanger. I am very happy with the results!
