Help MameWah Only Playes Music for my Consoles

[Mock]

I'm trying to reconfigure MameWah, but i'm having problems with the console part. I can get mame and Super Nintendo to work fine, but Genesis and Nintendo are giving me problems. Every time i try to play one of their games it gives me the loading screen on mamewah then it plays the game, but i only hear the sound, and i see no game nor can i close the game off, and then when i try to esc mamewah freezes up...Help!

Set 'Show DOS Box' to 'Yes'...

BTW I frequent the MAMEWorld board and here so no need to cross-post
