Okay, there's some progress.
Except for Top Gunner, it looks like you are having a problem with all vertical games.
And I noticed in the initial thread you said:
When I start games in Mame via MameWah
Does this mean that PacMan appears normal when you launch it from the commandline?
If not, then you need to look at autorol or autoror options in your C:\mame\mame.ini file (and set them to 0).
If it only happens in MAMEwah, you need to look at your MAMEwah mame.ini file settings, but I don't use it enough to advise you.
