Hi, I was given a DK TKG3-07 4-board set awhile back with the caveat that it probably didn't work. I hooked it up and it had lots of garbage, although it was partially playable. I did reburn one of the character EPROM's which had a broken leg. Anyway, I got it out today and started swapping parts with my working 4-board set (which I'm using for D2K). After all the swapping, here's what I've found (pics follow the description):
CPU and Sound board both work fine, although the bottom left pin in the socket of the Z80 is broken, it seems to contact the pin fine, or else it's not used.
VID board makes the beams on the barrel board all messed up. They don't slant, even though when Mario walks, when he starts going up hill, he actually goes up hill.
CLK board causes the sprites not to display, and all the fixed characters to be halved/doubled up.
Here's images of what each one does. All were done with the CPU and Sound board from the bad set (which, as stated, both work), they also had the ROM's from my good set in them.
Bad CLK board with my good VIDEO board, no moving sprites:
Title screen, you can see how all the text is halved/doubled up, and Kong is missing from the title screen.
Bad Video board with my good CLK board. You can climb ladders until you jump, then it messes up your location on the screen:
The game is still scoring, even though the scores all show 0's, as I was able to smash a bunch of the barrels grouped at the top and get enough to make the scoreboard:
Both bad CLK and VIDEO boards together:
