@mitu Seems so. Thanks for your suggestion.

I still don't know how to do it. I have tried but it doesn't work

@jmcall10
I understand you know how to copy Atari ST games (.st files) to the Atari ST Folder (/home/pi/RetroPie/roms/atarist).

The next step in the doc is to copy a file named tos.img into the bios folder (/home/pi/RetroPie/BIOS).

For some reason, you sound like you suddenly "have no idea what to do" at this step. Why not.

step by step:
1/ On your PC, open your web browser, go to Google (it's a search engine), type "tos.img" in the cell. Click on a random link from the results, read the page that just opened until your eyes see "tos.img" on your screen. Click on that tos.img link to download the file tos.img to your PC.
2/ Do exactly what you did when you copied .st files, except it's no more a .st file, it's a tos.img file now, and you don't copy it into the roms/atarist folder anymore. This time you have to copy this tos.img file into the BIOS folder.

@chiwaw Thank you for posting this. I know this thread is old but I wanted to say thank you, and also to say this is what I am trying to set up, essentially a retropie build that lets me use old 8-bit computers with the basic interpreters.

I have a ton of 1980s programming books from when my local public library got rid of them, and wanted to type in programs and save them. It's not well documented at retropie, recalbox, or other places as to how to launch these emulators into the computer's default BASIC interpreter. If you want to write BASIC programs, this is a must. I'm hoping this comment adds some phrases and words that would increase search result hits to this post. I've been trying to figure this out and every search I've tried has come up with squat until today when I put "BASIC interpreter" in quotes into google.

if your hostname contains win, it would try to build the Windows .dll.

Like 'Darwin' :) But yes, thought about the same when I took a peek there.

I tried to do it. It's too fast ! When I define up / down / left / right, I've each time one key which is detected by another. For exemple : the hatari asks for up, I move up the joystick, it detects the up and quickly passes to down and also detect the up.... is this any file to configure from ssh ?

Try updating the lr-hatari emulator from source, I think 2 player support hasn't been added until recently.

@mint OK My fault. It runs OK with another different disk image.

@sniper22b said in Cannot get Hatari Emulator to show up:

es_systems.cfg

You seem to have a customized es_systems.cfg - how did you install RetroPie ?

Pi Model or other hardware: (Zero Pi, Gameboy Zero)
Power Supply used: (Batterie)
RetroPie Version Used (4.4):
Built From: (Pre made SD Image on RetroPie website)
USB Devices connected:
Controller used: gpio
Emulator: (hatari)

Hi, I'm also in the same situation... I did an installation from source an leave alf day and night, it tooks almost 6hs :o :/ and is not working on my Pi Zero W. I never tried to install from binary... Is the only way to get it work?

Thanks for all your help.

The RPI zero/1 is not capable at emulating the ST at full speed.

I saw this thread, so I set up lr-hatari, got it working, and updated the docs, mostly just from the core's github readme. It worked pretty much first try, but the docs previously only covered Hatari standalone.

One thing I am not clear on is how you get the core to look at different BIOS files in order to emulate the STE or Falcon, but I haven't tried that yet.

I see lr-hatari can load an .m3u to allow disc control from retroarch. It will be automatically read from an uncompressed zip along with disk images.

Edit
It won't work within a zip, but works great loading directly from an m3u. Also, the disk image extension cannot be changed (eg. .disk1).

I changed the disk extension to uppercase and removed it from es_systems.cfg

I suppose you could use a hidden folder as well.

@RetroResolution Thanks for taking the time to write this post, helped me :)

@WilsonB
Update...
Fixed it by changing default to hatari-use-hatai-cfg

Sudo nano emulators.cfg
default = "hatari-use-hatai-cfg"
