I would eliminate that black wire connected between the coin switch and the start button.

Then I would then desolder a lead of the coin switch to eliminate the possibility that the coin switch is shorted
or stuck in the "on" state.

When the machine is turned on, any remaining credits should be decremented to zeros.

Once the machine is on, you can increment the credit counter then use the start button. But the machine has
to be on (working.)

I am suspicious of your micro switch wiring. There are three lugs. Your first lug is broken off with evidence of previous soldering activity. This may be the normally open lug with the center lug used as common. The black wire with white tracer is currently and maybe connected to the normally closed lug as it appears there has been some less than competent solder associated with this micro switch lug.

Remove the black wire with tracer and your free play hack from this lug. If you allow the black wire w/wire nut to remain connected to the black wire with tracer you shouldn't lose your free play and you have removed any micro switch interaction from
the circuit as the micro switch isn't being used anyway.
