Konami Jail Break arcade pcb repair

Essentially the same fault and repair as my earlier Green Beret fix which is almost the same board.  Corruption in sprites and the corruption was in ‘screen space’ as opposed to moving with the objects.

The 4 RAM chips in the top right of the board next to the square custom are used as line buffers for the sprites.  Replacing these fixed the sprites.
