Full screen advmame



  • Hello everyone,

    I would like to have all my games under advmame in full screen, but I do not find how to do it, here is my file advmame1.4.rc

    advmame1.4.rc

    How to modify it to have all my games in full screen?

    thank you in advance

    Do you mean fullscreen, as in the game's original fullscreen presentation, or fullscreen as in stretching the image to fit a 16x9 widescreen display? If it's the prior, AdvanceMAME should be defaulting to that presentation automatically and something could be preventing it from displaying the image correctly. If it's the latter, try changing display_aspect auto to display_aspect 16/9 in /opt/retropie/configs/mame-advmame/advmame.rc. You may also need to change display_expand 1.25 to display_expand 1, but maybe not.

    You might also try display_expand 1.33



  • @mediamogul said in Full screen advmame:

    display_expand 1.33

    display_expand 1.33 does not change anything.
    Can not put games in full screen 16-9

    I'm afraid I'm about out of ideas. I have display_expand set to '1' in order to display the image as it was originally intended. I've never really gone in any other direction before. It could be that display_magnifysize needs to be set to something besides '640', or even a particular combination of the previously mentioned settings. Perhaps @caver01 knows of a solution.



  • @cyclair When I looked at your linked .rc file, I see:

    display_aspectx 4
    display_aspecty 3
    

    These should be changed. Now, if you are saying you already tried that, I would suggest changing from AdvanceMAME 1.4 to the newer AdvanceMAME, which is 3.7 at this point I believe. It uses the same romset, so no extra work there. But, the config for aspect ratio changed. The current way to capture this would be:
    display_aspect 16/9 according to the current documentation.

    If you also set display_expand 1.78 this will stretch the image to fill a 16:9 display. I just tried it with Gauntlet II and it was fullscreen.

    OPINION FOLLOWS: It looked awful. The game was filling my big TV, but it was squashed. Round things look like ovals and everything is just distractingly stretched.

    I can only imagine how bad vertical games would look.

    I think you would run out of stretch parameter, as the max value is 2.0. Running 1080p at that stretch factor, you would end up with 150px pillarbox borders on the sides.

    So, it is important to note for @cyclair that if you are planning to fill the screen with vertical games too, you will only get to stretch those to 84% of the widescreen at display_expand 2.0.
