I was messing with my crystals castles cocktail and was testing some boards. First thing I found, rev2 of the roms will not function correctly in the cocktail. You cant make it work with player 2's controls (They just duplicated player 1 and no screen flip). Rev3 and rev4 work fine in a cocktail.
I was able to find a working pcb and fix my cocktail, but I have 2 pcbs that are close and have graphics problems. I was hoping to fix one or both(I have a 3rd pcb that has a broken crystal).. Both boards say rom and ram are good during bootup. I have tried swapping every socketed chip and no change on both boards.
1st board works but it has bad graphics on the motion objects. You can see the lines in bently bear and the crystal balls. here is a pic
2nd board has a different problem. Its like your looking through green shutters.. Its also drawing some garbage above the crystal balls when they start in the right corner.
Also when I put #2 into test and I call up the grid, I get this screen. I am pretty sure its supposed to draw a normal grid..
Any ideas on fixing these 2 pcbs?
