Adding Gameex/MAME to my Pinball cabinet...Need help with monitor setup

[wrd1972]

Ok I am adding command-line MAME and Gameex to my 3-screen Pinball cabinet but I need some help with display setup. I dont want "full-screen" display because its simply too big. I have found that turning on the Arcade VGA setting in Gameex settings (Display) makes for a very nice screen size in the middle of the main screen.

Ideally, I want to use the 40" LED TV (playfield in the cab) for all MAME games...vertical and horizonatl formats. I currently have the Vertical formats working fine but when a horizontal game loads, is stretched into a vertical format. I want these horizontal format games to appear properly on the screen.

Is it possible to have both format screen appear properly on the 40" TV (playfieldscreen) in my cab without having the horizontal screen size affected?

Any help appreciated.

Thanks

When you have a game loaded in MAME. You can press TAB key/video options/ and there is a Rotate feature.

To have the rotate feature enabled globally for all horizontal games, just copy and paste your mame.ini to a folder called ini that's in the same location as mame.exe or mame.64.exe

rename it to horizontal and set either rol 1 or ror1

If I'm understanding what you're wanting to do that should remedy your problem
