Crazy Kong Cocktail 2 layer
Problem: Colours missing. Crazy Kong missing completely but you can see the black outline.
Fix: Broken legs on colour prom @ 9C lucky I have spares.
Problem: Crazy Kong is all sliced up vertically with double parts of him showing.
Fix: Bad track bottom board running to 74ls273 @ 2D pin 7.
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
