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
