Well now that the inputs and door sensors are working, I thought I would look at the machine counts screens.
It seems that I will need to map the memory locations for each of the amounts, but most appear to have zeros in them.
The values are stored in a 4 byte BCD format and support values from 0 to 99999999.
I can't seem to get past a certain screen and advance to the current game display screen. I need to figure out what is blocking me from going forward.
