I am a recent user of Linux Mint and I came across a problem, I like to play with the window stretched, but when I select the option in emulation settings, it does not have the button to apply, so how do I exit by clicking on the close button the unsaved option and the game runs only at 4.3. Is there a solution?
Do you mean this window?
Maybe you have to resize your window manual (Using your mouse), might be hidden.
That might happen, if you're missing dependencies related to GTK, so the UI will also not look very modern. If that's your case also, try:
Additional install:
- sudo apt install gtk2-engines-pixbuf:i386
- sudo apt install gtk2-engines-murrine:i386
- sudo apt install gnome-themes-extra:i386
- sudo apt install libatk-adaptor:i386
- sudo apt install libgail-common:i386
