So I've been waiting for the release of the Sega System 18 Multi. I bought a Shadow dancer a while back. I've been trying to get it working correctly. I've scoured the internet looking for information but there really isn't much regarding the Sega 18. The screen displays duplicate text and images and have no sound. I replaced several eproms on the roms board with 27C2001 and it has made the image better but I still have graphical glitches and duplicate text, images and no sound. Any ideas where to look? Here are the 3 roms I haven't replaced yet.
I looked for bad traces and found none. Neither the CPU or Z80 are encrypted. Here is a short video.View: https://youtu.be/jZlAvin5s4E
