Been working on a DK 2-bd set today around football. In spite of what I've read online, I could NOT get it to work with a DKjr Video PCB that is known good. I finally got a DK Video board working.
So - the only real issue is that there are some minor sprite sparkles in various places. I usually see a couple that repeat in the barrel stack to the left of DK on the girder screen. Sometimes a couple will pop up in the moving barrels. Sometimes I'll see a little horizontal line pop up over Jumpman's head when he is moving, but not always. There is some type of line or something that pops up from time to time above the girl's head beneath the score that stretches the width of the screen.
I've swapped all the socketed chips out with another set, with no change. I've shot every part on both boards with freeze spray without it going away.
Like I said, it's minor, and not really that noticeable, but I notice it. Anyone have a bright idea?
As for the ROM question - during my troubleshooting, I verified all the ROMs on my ROM burner using ROMident. The two Sound chips 3F and 3H came up as unknown with a different checksum than what MAWS shows, although MAWS shows different locations and checksums, which leads me to believe those are for the 4-brd set. I checked both sets of ROMs that I have and they both came up with the exact same checksums. I can't test the sound at the moment (on my bench), so should I be worried?
