I've noticed this too, but couldn't track down the issue yet. Raster lines shift 16 pixels to the left each line, but I can't locate where in the code this is happening. It's weird that some games from MAME work, but others don't. Also, the problem only occurs on windows - RPi seems to work fine.
If you choose "alternate render method" in the mame core, the games that showed the "shifted lines" behaviour (for example Gauntlet or Burger Time) work fine. Maybe there are XY resolutions that RetroPlayer doesn't like?
Also, in the DosBox core, with the vgaonly mode the dos screen at startup is shifted, but with the svga modes is good. But, in both cases, when the games begin (at least those I've tried) the audio can be heard, but the screen remains black.
