Title: invasion to mk4
Post by: mnegr454 on May 23, 2016, 06:14:06 pm
Have an invasion board that I would like to change to mk4 . What  roms do I change and where can I get them.  Does anybody here can burn the roms and how much does it cost.  I will read on it some more.

The PCBs are slightly different so can't be converted.
Regardless all of the Midway games from MK3 onwards have a protection chip (a PIC16C57 microcontroller) and you can't simply swap ROMs to get a new game.
I have an MK4 in a JAMMA cab which also has Ultimate MK3. Maybe I'll sell it if the price is right ;-)
Email me....
