Crazy Kong Falcon Original. Exactly the same board as above but had the old revision roms on it. I pinched the colour proms off this board and swapped them with what I had which is what the same as you see in most bootlegs.

Crazy Kong Falcon Original

I converted this one with the Falcon Part 2 rom set awhile back only just recently got the colour proms to match.

Problem: I've never really sat down and played this game only just realized that up and down were around the wrong way and it wasn't incorrect wiring of the harness.
Fix: somebody had used a 74ls367@2F instead of a 74ls368. The 368's outputs are inverted to the 367.

Crazy Kong Falcon Original. Exactly the same board as above but had the old revision roms on it. I pinched the colour proms off this board and swapped them with what I had which is what the same as you see in most bootlegs.

Problem: Dead board except for for some scrolling garbage. No clock to cpu.
Fix: Found a dead area of the board. There was a pull up resistor that connects to a heap of 74ls74 which was dead. this usually means there is a short somewhere. I had to cut each pin of the 74s until I found the one which was shorting. Found the bad one @7K replacing the chip the board fired up.

Problem: Missing sounds. mainly the coin, Kong jump and Mario's jump noise.
Fix: Bad LM3900 @1T
