Gpsp on retropie display scaling


New Member

I just wondered if there is a way to change the config file for gpsp to enable a 4:3 aspect ratio to fill my screen?

I've looked everywhere and can't figure out how to do it. There is a thread here talking about using a hex editor http://forums.qj.net/psp-homebrew-hacks-discussion/68110-gpsp-cfg-editing.html I have opened the gpsp.cfg config file with a hex editor and I can't make head nor tail of it... Plus this guide is about getting gpsp to run in 16:9.

I've also looked at this https://github.com/DPRCZ/gpsp especially the video.c file, but I do not know whether any of this goes into the gpsp.cfg?

And unfortunately I don't have display scaling options in the gui like here

Any help would be greatly appreciated!
