Yeah it definitely works, others seem to know the actual section to edit. I am just saying if you play normal fullscreen it will probably stop looking so terrible after a little while, you adjust. We all played them that way back when.

It doesn't actually mean that, it relates to old display modes that used non-square pixels.

This article explains better:

Uhh...I said that in my post that you quoted. charbon wants two things:

1) original aspect ratio (to correct for game being designed for non-square pixels)
2) fullscreen scaling without screwing up whatever the set aspect ratio is.

1 is solved by aspect=true, 2 is a built in feature of Dosbox as far as I can tell. Me saying that going fullscreen maintains the aspect ratio (i.e. doesn't stretch to fill the widescreen monitor) was a separate thought from the aspect ratio definition (something I clarified in that post). I simply combined the two thoughts into one sentence, that's all.

I was just disputing the bit I quoted, "Then whatever the aspect ratio is if you play in a window, that will be preserved when you go to fullscreen.".

The aspect setting only corrects the non-square pixel mode to 4:3, it doesn't maintain that in full screen or prevent his video card/monitor from stretching it out. It looked to me originally like you were saying that was a function of the aspect setting, sorry for misreading.

No worries, I could have wrote that better! Cheers. :)

TBH, I was quite tired when I was posting last night, I think it's plenty clear now.
