I have a Sega System 8 board that seems to have problems with displaying a few things.
The game is Sega Ninja. The board is in a Dynamo cab, using a Sega 8 to Jamma adapter. Sound seems to work fine, although I cannot coin the thing up to see what else might be wrong. Thats just one of the issues...
Initially upon receipt of this board, I slapped it into the cab and fired it right up. Checked voltages prior and after, and all is good there. Ive been running a few other jamma boards in there successfully, so the cab and monitor both check out fine. I noticed the first issue then.
There are a lot of things that dont seem to fill in properly with color. What should be there is just black. The text that says "Insert Coin", "Credits 0", etc all are black. The rest of the character sprites seem to draw fine, theres color but many things lack the correct color, or any color at all. I suspect a rom is bad. Why? well I looked over the socketed chips and I could clearly see a leg that was bent, unsocketed. Removed that one, along with anything else socketed and cleaned all the legs and reseated. Plugged the board back in, same issues.
Pretty sure this has a ROM issue. Most likely will burn up a set of those, if the flock suggests the same remedy. This game does have freeplay as far as I can tell, but whether that is on, or I try to coin up manually, I never see any credits applied or free play show up on screen (maybe it shouldnt, no idea). I will also say that I doubt the adapter is bad, but I have no other way to test it at the moment.
Any Ideas?
