Hello People

Had this version of Retropie running for awhile now and haven't had any problems until a week ago when the Mame emulator started displaying the games in the top LHS instead of full screen like it used to - see picture below
The kids had their cousins over last week and were playing it all afternoon so not sure if maybe a setting has been changed by accident anyhows I'm stumped

I've had a read through the forum and have tried changing the display settings in rpi config which were set to default, I change this to 1920 x 1080 60hz but that had no effect so have change back to default

The problem is only affecting Mame so it must be a setting in mame

I'm using ir-mame 2003

Has anyone had this problem and if so how did you fix it

Launch a MAME game, press a button to open the launch menu and see if there's a custom video mode selected. If there is, clear it.
