THAT WORKED, thank you so much!
The last problem i have, is i noticed while trying to fix the audio, that the pixels appear to be twice as tall as usual, doomguy’s eyes look very scary because of this, would you happen to know how to fix that too?
Again, thank you very much.
An edit to add some comparison images:
Top: Magic Dosbox
Bottom: Retroarch
Edit: So far i have worked around this by just normally using the 80% screen toggle, and that looks fine, and then the one program that smushes in 2d mode, i just use the 4:3 option. So all i have to do is switch it for that one program.
