I have been trying to fix a graphics glitch on my Aliens board. In test mode, ROMs J8, K8, J13, K13 are all marked bad. So I look at the board to inspect and wow, they're not there. Now this is really strange because the game works and plays fine, it just has some lines in the background graphics.
So looking at other boards on the internet, there are ROMs present in J2, K2, J8, K8, J13, K13, J19 and K19 where on my board, they are all missing.
Instead, this board also has a bottom ROM board plugged in where all the pictures on the internet show a single board. The bottom ROM board has 28 ROMs present on it (ROM Board MAX96M) So is this a different version? It has an official Konami sticker on it and looks legit. I'm a bit confused now how to troubleshoot my bad ROM check sums with so many on here.
