Kale, how did you get those graphics? This is what I see in MAME:

A complete mess as you can see smile

The controls seem correct, thing is these games come with a controller overlay that you put on top of the keyboard the 1/2 player buttons just happen to end up on top of the Home and Del buttons of the RX-78 machine. This is such a great oddball machine, a pity that its preservation status is so poor.
