Hello, not sure this is the right place to ask help anyomre (chat? mail?) anyway I'll give it a try.
I'm having this issue which I think I never had before, basically with my slot-4 certain games (i.e. Twinkle or Miracle adventure) boot normally the first time after writing to the flash, then when the second loops occurs, the cabinet resets (green screen)
i.e.
slot-1 = Mslug
Slot-2 = NeoSD (Twinkle)
slot-3 = Robo Army
slot-4 = Pulstar
cycle after flashing is Mslug, Twinkle, Robo Army, Pulstar...then 2nd loop kicks in after the jingle Mslug--->reset, Mslug--->Reset.
I tried changing slots but it's still the same when reaching the NeoSD slot.
Flashign Puzzle Bobble or Garou 2 Special works flawlessly.
