Ghost & Fruit Sprites look funny (Color Ram 2a-2d) FIXED
I pulled out this old project recently, intending to be productive while looking for new employment. Here's what I've done to it so far:
I pulled the board out for inspection and found corrosion on RAM 2C and 2D. (pic1)
Those got cleaned and reinstalled.
I put the board in a Ms Pac Man cabinet, powered it up, and the screen looked like a russian boot-leg. (pic2)
I pulled the board again, then slightly lifted 5E & 5F to reseat them. This revealed 3 broken pins.
I soldered new pins at E2, F2 (pic3), and F12. [no budget for new right now]
This worked great for a day-or-two in the Pac Man cabinet after fixing the monitor. (pic4)

Today, I powered it up and the ghost sprites are buggered. (gif5)
Does anyone know what chip/pin would control just the ghost & cherry sprites?
*Also, the credit switch on the coin door needs to be held down for a second-or-two before it registers a credit and changes the coin counter. The red credit button next to the test switch works without issue, though.
