1942 Second Fire Button

[monty124]

Hey there, great project!

I'm working on a highly customised version of this using a CYD but I have a general question.

I was wondering, is there a possibility of enabling the second button on the control board as a second fire button?

on the original 1942 for example this was the loop or flip action in the game (if i recall, left was fire, right was flip; or upper lower, it was a long time ago) either way this was a 2 button game iirc

could this be an optional enable if required?

I'm able to break out additional buttons as IO's for the start and coin function so this would be great if possible?

I tried to take a look into the code (in 1942 specifically) but it started to get a bit above what i understand :(
