Hatari 2.0 released

AmigaGamer

Just noticed this has been updated today, testing it now so figured id post up my current findings.

Seems to build fine by just changing

function sources_hatari() {
wget -q -O- "$__archive_url/hatari-1.9.0.tar.bz2" | tar -xvj --strip-components=1

to

function sources_hatari() {
wget -q -O- "http://download.tuxfamily.org/hatari/2.0.0/hatari-2.0.0.tar.bz2" | tar -xvj --strip-components=1

not sure on its effect on IPF files yet as theres a small patch in the retropie script on 1.9
SDL2 scaler now gives a full monitor sized image. the downside of this is it breaks the 4:3 aspect ratio (there may be an option i havent found yet)

Tested on a pi3, latest raspbian with retropie installed. Only diference i can see over a "default retropie" build is ive manually updated SDL2 libs to 2.0.5 ( i think retropie is on 2.0.4?)

Thanks. Have made a ticket here - https://github.com/RetroPie/RetroPie-Setup/issues/1739

Will look into it.

looking at video/performance options at the moment. Im trying to remember where we discussed all this stuff (likely on petrockblog or github) previously , theres a lot of relavent notes somewhere

--zoom 1 disables the internal scaler so better for performance , the menus look awful though
-- zoom 2 (default) looks a lot nicer.

theres now a 3rd option to consider.
--zoom 1 on command line and enable SDL2 Linear Scaling in the video options. Gives a blurred upscale that gives more of a CRT look/feel

@AmigaGamer with our SDL2 it might be possible to improve this - if you can get hatari to use a native resolution / unscaled and set the env variable SDL_VIDEO_RPI_SCALE_MODE=1 it should use dispmanx for the scaling.

@buzz yes this fixed the aspect ratio launching through bash shell using
SDL_VIDEO_RPI_SCALE_MODE=1
export SDL_VIDEO_RPI_SCALE_MODE
then tested hatari with
hatari --zoom 1 or hatari --zoom 2
emulationstation is ignoring it though, im not sure if its not seeing the variable or something with my launch config

interesting i never knew about that SDL2 var before , will give it a try with the SDL2 dev branch of FUSE later on today https://sourceforge.net/p/fuse-emulator/code/HEAD/tree/branches/2014-12-28-sdl2/ https://sourceforge.net/p/fuse-emulator/patches/326/

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)
