Libretro Hatari - How to install?

[Pyjamarama]

Since I cannot map buttons to emulator actions from within Hatari, I would like to give a shot to the Libetro Hatari test core here: https://github.com/libretro/hatari

Can you guide me how to install it?
If I install it, will RetroPie give it to me as an option for Atari ST roms?

I have a pi3

Thanx!

I had the following answer in the libretro Hatari github
https://github.com/libretro/hatari/issues/11#issuecomment-257352187

You can build this by going into the top-level directory of the source tree and typing:
make -f Makefile.libretro
Beyond that, you'd have to talk to the RetroPie folks about how to integrate it, etc.

create a new file nano ~/RetroPie-Setup/scriptmodules/libretrocores/lr-hatari.sh and paste this into it

#!/usr/bin/env bash

}

function install_lr-hatari() {
    md_ret_files=(
        'hatari_libretro.so'

        'gpl.txt'
    )
}

function configure_lr-hatari() {
    mkRomDir "atarist"
    ensureSystemretroconfig "atarist"

    addSystem 0 "$md_id" "atarist" "$md_inst/hatari_libretro.so"
}

then go into RetroPie-Setup and install it from the experimental section.

if it installs ok, you will be able to select it from the runcommand launch menu

Thank you @BuZz

I will install it when I get home and let you know of the outcome

[Pyjamarama]

Just installed it but when I am in the Launch menu and press to select the default emulator, I get a black border in the bottom of the screen which says something about arguments (too quick to read) and starts the game with the default emulator (hatari fast)

I went to dev/shm but the logs did not contain the error

I manually edit the emulator.cfg and put lr-hatari as default.

It cannot run the ipf files (it pops up an error messagebox) and in the .st files it just goes back to the games list.

I have put the tos.img inside the lr-hatari folder but with no success.

[Pyjamarama]

I deleted the lr-hatari.sh script from inside the libretrocores and tried to install lr-hatari from the RetroPie 4.1 envioronment.

I get only a Install from Source selection and after that I am getting this error message:

lr-hatari-patch

/home/pi/retroPie-Setup/scriptmodules/libretrocores/lr-hatari/01_libcapsimage.diff failed to apply

the log

...

lr-hatari patch /home/pi/RetroPie-Setup/scriptmodules/libretrocores/lr-hatari/01_libcapsimage.diff failed to apply

any help appreciated

It's broken - I will fix it. Note there are problems with this core still - I had to put the system os in the /opt/retropie/emulators/retroarch/bin folder for it to find it - although may be fixable with a custom hatari config.

[BuZz]

should be fixed now. I had forgotten to commit a file to the repository. You will need to update retropie-setup script.

[Pyjamarama]

Yeap. You are ace.

The core has definetely issues. I placed the TOS image even inside the retroarch bin folder as you suggested but I cannot have any .st game file to work. I am always thrown back to the rom list screen. It does not support .ipf game files (at least I get an error message for it)

I hope the guys can improve it in the future. Good addition to RetroArch arsenal :)

[BuZz]

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.
