Dear brother,

I have a question on the physical connection.( not sure do you know this)
From the setting menu, there have a control of the coins output. In real machine, the coins will drop out after the you pass the button or play the game if you got metal.
If the metal can't (the stock is empty) come out, it will have error message. (I guess you have amend it to Ignore it. because it still can pass without checking, right?)

My question is if it possible to pass the message to com port ? I try to add a control board to get those message from the comport or usb etc.. so that make the this machine work.
