New WORKING clone

E.D.F.: Earth Defense Force (set 3) [Sergio Galiano, Recreativos Piscis]

There are no date strings on the program ROM nor text or warning screen which could hint if this is a newer or older version, so I simply added it as "(set 3)".

I also added the dump of the MCU in "peekaboo" on the same driver. This time I only added the ROM entry and has no real effect in emulation, it needs to be hooked up, because it works differently than the MCU in other games on the same driver.
As far as I can see in the initializing code, there are some differences in the device configuration:

  • Port1 is used as output instead of input
  • Port3 is used as standard output port instead using /RD, /WR... signals.
  • Timer 1 is used for some task, and INTT1 flag is enabled for that cause.
  • Port7 is also used as output port (not used in other MCU dumps)
