I want to use FCEUX (2.2.2 on Debian unstable) in fullscreen mode using the maximum size of the monitor but keeping the apsect ratio. My monitor has a native resolution of 1024x600.
I read the manpage and thougt I understand it but I didn't. In some configurations the picture doesn't use the complete size of the screen. In others the picture is scaled to the complete (X and Y) screen but without keeping the aspect ratio.
It would be nice to use one of the scaling mechanisms of FCEUX to have better picture (without pixel stairs). But it is not a must have. A fullscreen picture with pixel would be no problem at all.
This are the (maybe) relevant parts of the config file.
