Ring King not working (ROM or mapper issue?)

[eightbit]

Does "Ring King" work for anybody? I am trying to determine if it is my rom or a compatibility issue with the core. Upon launch the sound works but the picture is black. When the attract mode (demo game) comes up you can see the boxers but not the ring or background (again black). Or maybe missing mapper?

I was having issues with some "obscure" games in the NES core. Then I've realized that No-Intro pack has wrong headers for some ROMs. So I've used this tool in order to correct the ROM headers:

After that, I'm yet to get an issue with any game. I didn't try the specific game you've mentioned, but I do recommend going ahead and fix your NES ROM headers with that tool.

Cheers!

I was having the same issues with black background, etc. as eightbit, but the method bootsector mention has fixed it!!

Thanks!!
