Planet X2 controls

Hey there Void,

I just got my Evercade VS and with it the Home Computer Heroes Collection 1 which contains Planet X2 (c64 edition).

Now for some reason whenever I hit the unmappable R2 it goes into the Quit Menu prompt which asks for a Yes or No. But whatever input I do it will not react.

The Unit Hotbar continues to work but doesn't do anything. (It's also a total mess which can lock up the controls) and when I restart the Game it doesn't react to any input I make as well.

Anyone got an idea how to solve this issue?
