Screenshot in wrong format

hello, I noticed that with “GPU Screenshot” option disabled, screenshots of some cores (for example PUAE and Stella) are saved in an incorrect format. how can I fix it?

Example PUAE:

Stella: Keystone Kapers (1983) (Activision, Garry Kitchen) (AX-025, AX-025-04) ~-241203-144652

This is the correct format if “GPU Screenshot” is disabled. You need to have a video driver enabled that supports it. The Gl/Core ones do, I don’t remember if any else do, just try. Otherwise, you have to use an external tool or available OS functions to take screenshots of the actual screen.

@quellen Non-GPU screenshots are from the image directly taken from the core without any processing, think of them as the purest image output from the game. Scaling, cropping etc are done later by the frontend (or original hardware).

I always save non-gpu screenshots since they take up much less space and can be processed later for whatever you may need, with better results.

The only hope for non-stretched raw images is if the core supports forcing different resolution widths, and PUAE sure does.

You can enter Core Options, then under Video set Resolution to Low 360px and below Line Mode select Single Line (PUAE).
