Aspect Ratio - Upscaling

[Who_Dunnit_Roger]

If this has been answered already, apologies I just cannot seem to find the topic. My MAME has consolidated the game to the middle of the screen taking up about 40% while the bezels/bars take up 60%. Keeping the game undistorted is key but how do I increase the game to be say 70% and the bezels/bars 30% etc...I hav tried everything, it either gets overstretched or parts of the fame get lost behind the bezels etc. Thank you the help.

Can you share a screenshot of what you're seeing?

@JoeViking245  thanks for the help. I have seen it larger on others previews, so trying to figure out how to reduce Bezels by 50% while increasing the played by approx. the same.

What's your monitor size?  1920x1080?  It looks like it's not going to the bottom (and top?) of the screen. (Maybe that's how your monitor is, or you messed with the .lay file? Not sure exactly how that works.)

If that were "fixed", you'd gain a little more real estate. 

Decreasing the size of the left/right sides will of course increase the width of the playfield. But will also distort (stretch) it's 256x224 (3:4) resolution. 

(I think) to do what you want, you'd need to find/create a bezel image with narrower side bars and adjust the lay file to match.

What you may have seen is someone had a bezel for 7:8. Which would make it a little wider.  When you go into the Tab menu - Video during gameplay, you can switch between Bezel (or 3:4) and 7:8 to see the width difference.  Turn off Maintain Aspect Ratio and see how out-of-wack it can get.
