The game was working good except the sprites were all missing some lines

The board is using some unreliable drams 41464 from Fujitsu similar to the ones used on Konami Haunted Castle or CPS1 A board.

I bought some units from Aliexpress , put some handmade socktes and changed both to be 100% sure

Turned out only one of the two was faulty, in anycase the graphics were 100% fixed
