I'm stumped on another project. I recently got a Bubble Bobble board and when I wired it into my cab, the game boots up into attract but won't take any credits and the screen is divided in two - the background images on the left and all sprites on the right. I have no clue what might be causing this. i'll try and attach some photos - thanks again!

I've jumpered JPA and JPB still no coin up - I think the test screen is supposed to show colour gradient in the middle of the grid but it seems to be black in the middle (although there are good colours in normal mode) and the grid is half off the screen to the left just like the title screen

well found a busted pin - fixed.  -  and a diode soldered in backwards - fixed - still the same issue though :( anyone got a lead on this??? its seems to be a pretty specific issue

Where's channelmaniac when ya need 'em - piggybacked the 283's and 157's no change.  when I switched back one of the diodes that was soldered in backwards by a previous person it seemed to make it slightly worse?!
