Summary 08705: Many sets on system1.cpp: Auto-incrementing coin counters on boot
Description When running a game, the coin counter numbers in the machine's cfg file will increase by 1 on each start up even though credits are not being added by the user.
Steps To Reproduce 1. Run any of the affected games.
2. Let the game run for a little bit, just don't add any credits.
3. Exit the game, go to your cfg directory and examine the game's cfg file. The coin counter numbers should be at 1 now.
4. Run the same game and repeat step 2.
5. Repeat step 3, and the counters will now be at 2.

8255 tristate issue again.
Though NMI has a pull up resistor according to schematics. And I assume the MCU interrupt pin has it too.
