Megattack
Pot Of Gold (Leprechaun)
- Leprechaun and Pirate Treasure were made for the Moppet Video arcade series
(Enter-Tech arcade cabs aimed at younger children). That's why the games are
so easy.
TODO:
- The board has, instead of a watchdog, a timed reset that has to be disabled

to that pin in the log. Missing support in machine/6522via.cpp?
- Investigate and document the 8910 dip switches
- Fix the input ports of Kaos
- Some of the games do unmapped reads all over the place, probably just bad
programming. One of these is piratetr, and it will lock up eventually when
reading from VIA1. It's possible to fix with a simple wire mod/pcb cut trace,
like done with piratetr_main_map. Let's assume they did something like that.
