Closed problem report

Swapped the wiring from the aftermarket credit-add switch to doubled-up wiring on the Game Start button. This bypasses the 1-credit problem in https://flipfix.theflip.museum/problem-reports/77/.

This cross-wiring also makes for a more obvious button press, one that our visitors can find.

Also: re-soldered the Test Mode switch wiring so that we can actually enter test mode.

Also: pulled the ROM, cleaned contacts, and replaced it.

Repaired the already installed credit adder button. Can now push button to add credits. Exhibits weird behavior still where the amount of credits is limited to 1, but you can start a 4 player game if you push start, add credit, push start, etc. Also we should increase the replay score with the dip switches now that we have this functioning.

While trying to figure out how to set to free play, I played a bunch of games in a row and it was either matching for a credit or recognized a high score after every single game. No matter what the score was, it gives out a free credit after every game. May be a problem that gets resolved when game is set to free play, but it was odd behavior
