I messed up some settings in the MAME emulator while playing Mappy, causing this weird display where the game/emulator moves to the bottom right corner of the screen and stays there. The menu goes along with it, so I cannot see where I'm going on the menu. Is there someway to undo this change, or set all the settings back to default?

Yeah, that happens with one particular setting in the MAME video settings. If you try to change the aspect ratio, the emulator's screen will bug out. Here's how to fix it.


Navigate to your VizzedRGRPlugin folder on your PC. It should be located at "C:ProgramDataVizzedVizzedRgrPluginUser-593909MAME". Then, find a file in that folder titled "mappy.cfg". Delete the file, and you'll reset your settings for Mappy. I recommend doing this, as it probably won't take too long to revert the rest of your settings back to what you've had.


If you want to keep your settings for Mappy, you can instead open mappy.cfg in Notepad, and delete the three lines I highlighted in this picture:





The part that says "Pixel Aspect" may or may not be different depending on what setting you've changed it to. I tried to copy and paste the text from mappy.cfg into my post, but it doesn't let me put it in for some reason, so I had to use a picture. Anyway, hope this helps.

Thank you so much for helping me! I will see if it works and try to update the post.

The path that I posted should be this instead:

C: --> ProgramData --> Vizzed --> VizzedRgrPlugin --> User-593909 --> MAME.

Replace the --> with the backslash character. Vizzed does not allow backslashes to appear in posts for some strange reason. \\\\\\\\ For some reason, those show up.
