Mame not saving when I turn off maintain aspect ratio?

[jimbone007]

When I go into the mame menu  video options/screen #0 and turn maintain aspect ratio off it works but then when I exit the game and relaunch it reverts back to being on. How do I get this to save? Also can this be applied to all mame games in a certain collection. Light gun games for example?

Maintain Aspect Ratio doesn't appear it can be saved on a per game basis.  As you discovered.  But as [almost] always, there are options.

option 1

You can turn it off globally by editing mame.ini and changing "keepaspect" to "0" (zero).

 

option 2

Though a bit tedious, you can create game-specific ini files that has a single line... "keepaspect       0".  Save the file with the same name as the ROM and a ".ini" file extension.  Save this in the ini folder under MAME.  example:  D:\Emulators\MAME\ini\area51.ini  This method would need to be done for each game you want to have it Off.  If for some reason/somehow there's already an ini file for a specific game, edit it as was done above.

There are a few ini file types that can be used for specific configurations.  One of them being game-specific as in the previous option.  Controls Input ("light gun games") is not one of them.  I really don't know anything about lightgun machines (cabinets), but I do believe most (all?) use CRT monitors.  Monitor types is one of those 'specific configurations' that are available.

If you want all your [other] games to have Keep Aspect "On", leave your mame.ini file alone ("keepaspect  1").  Then to have all games that use a CRT monitor use "Keep Aspect OFF", create an ini file just like the game-specific one above, but save the file as "raster.ini".      D:\Emulators\MAME\ini\raster.ini

Thanks for the info. I think I'll just create separate ini files for each game since there aren't that many and the majority I want to maintain the aspect ratio so they have  bezels.

Yeah I thought this to be annoying as well. I wonder why the devs don't let the "keep aspect off" save per game. It does it for whatever aspect you choose and all the inputs per game. 🧐
There are some games I want stretched and some left alone.
