I have a Mortal Kombat II cabinet (which was originally Street Fighter II) which has a Wells Gardner 25K7193 monitor installed in it, which has been long discontinued. I cannot find any documentation on it and when I try to configure AdvanceMAME with advcfg.exe there's no preset for it. When I use the most similar model (the K7200 or something) it comes out like this:

Does anybody know what to do or how I can get this working?
