I know is old thread but i want to let know lr-hatari is fixed now and works, big step from standard Hatari imho. Hope that helps people interested.

Unfortunately it does not seem to work.
I hpe that the regular hatari gets button configuration support so no keyboard is needed...

@spudsmctoole I'm guessing that's a no, then?

The Hatari version in RetroPie is 1.9.0 - see the install script for this emulator https://github.com/RetroPie/RetroPie-Setup/blob/master/scriptmodules/emulators/hatari.sh. However, it might be only the hatari-wii has this feature implemented.

Ok, I tried turning off dithering, and it didn't seem to make any difference.

I'm still getting artifacts, like echo-type sounds, sounds that go on longer than they should etc.

I have listened carefully to games that I am very familiar with on other systems, and this definitely only seems to affect Hatari.

Indeed it does, many thanks for the quick fix

to get it to work from ES, put it in the emulators.cfg launch line in /opt/retropie/configs/atari/emulators.cfg like SDL_VIDEO_RPI_SCALE_MODE=1 $md_inst/bin/hatari --zoom 1 etc

you can change the pixel aspect ratio also: (note these options are specific to our SDL2 - our SDL1 also has similar options)

Yeah it needs work. It may have been best left out tbh, but I was short on time to test, so I thought it would be ok to leave it in experimental.
