Universal Games

Jamma Adapter for Universal games such as:
Lady Bug
Mr.Do
Mr.Do Castle
Mr.Do Vs Unicorns
Do Run Run
Mr.Do Wild Ride
May work with other games but I couldn’t test

The adapter comes with inbuilt sound amp with independent Volume / Gain / Bass trimmers for games which don’t have a sound amp on board

For Lady Bug which comes with an amp on the pcb, you can switch off the adapter amp
