I checked on my system and using lr-atari800 should start the game, though the checksum I have is different (45f8841269313736489180c8ec3e9588) than yours. I also tried a different game (BerZerk) and it started without issues.

Make sure you're using the latest lr-atari800 and remove again $HOME/.lr-atari800.cfg. I don't think the latest version of the core uses a .cfg file anymore, but just delete it for good measure.

@mitu I am good to go as well. Thanks for the fix.

@mitu @RapidEdwin08 I had tried to use the A key I had selected above but it didn't work. I finally got it set up but I don't know what if anything I did differently.

I think I got both the keyboard and controller working and moved on to getting the Atari 5200 games to work. That's also a lot move involved than I would have thought but I'm working my way through the documentation.

Thanks for the help! I really appreciate it.

I just upgraded to a Pi 4 and Atari 5200 works now!

However I still get segmentation faults in runcommand on a Pi 3.

Both are running Retropie fully upgraded with the latest lr-atari800 binary.

So I guess if this is happening to you, ditch the Pi 3 like I did.

I solved the problem. It was easy. An update from the lr-Atari800 emulator helped.

@sportster you can do it manually just push Y button and homescreen button on the game .

@pmdci you have to open the Retroarch menu when you are running a game. Go to Quick Menu, Options, then Controls. Set the player 1 to Atari joystick (or something similar to that). That will allow you to use the start key on your controller.

Same for the Atari 800 if you are running that portion of the emulator.

@JuanZt set it, then choose Save Core Override. Or, find the line in the .cfg and manually edit it.

@jamrom2 thank you so much for trying to help me. it seems 5200 emulation just isn't in the cards for me.

I actually found the old image had backed up on a card in a drawer. I booted it up and 5200 worked without a hitch. I figured, jackpot, I'll just transfer the settings and configs to my current image. no dice.

short of finding a pre-converted 5200 romset somewhere I don't think it's going to work out.

Wanted to say THANKS for the "menu_enable_widgets" fix and to share some more info.

First, it was interesting that ROMs were fine and that ATR disks were all failing.

I tracked down the segmentation violation in the /dev/shm/run command.log:

/opt/retropie/supplementary/runcommand/runcommand.sh: line 1283: 31257 Segmentation fault /opt/retropie/emulators/retroarch/bin/retroarch -L /opt/retropie/libretrocores/lr-atari800/atari800_libretro.so --config /opt/retropie/configs/atari800/retroarch.cfg "/home/pi/RetroPie/roms/atari800/Mule.atr" --verbose --appendconfig /dev/shm/retroarch.cfg

I took a look at line 1283:

eval $COMMAND </dev/tty &>>"$LOG"

All this is doing is running the right command, explicitly getting input from the tty, and tying file descriptors to the log.

I ran the command from the console and it worked fine without redirecting STDIN/STDERR. It also worked fine just redirecting STDOUT (fd 1). But every time I redirected STDERR (fd 2), I got a segmentation violation.

Not sure what exactly the widgets have to do with this, but apparently they do. If anybody wants a strace of this I would be happy to provide.

I hope this is helpful, and again, thanks for the fix!

@Muteki correct. These files are mostly copyrighted (there's a few cases where vendors have permitted distribution), so we can't install them automatically.

Some systems run without. Eg. Zx spectrum, as the bios is included due to being permitted by the copyright holder (in this case Amstrad). Or because they use a replacement copyright free bios. Eg. There is one for the Amiga for example.

How are you changing the emulator configuration ?
Since you're using the lr-atari800, there's a Core option that sets the machine type, when you change that option it should be automatically saved. Is this how you change the machine type ?

@dankcushions Here are the 100 core option files I made for the 5200 content I have. These are the .opt text files only.

Core option files for 5200.zip

I put them in \RETROPIE\configs\all\retroarch\config\Atari800\ and so far I think it's working although I haven't tested all of them.

Cheers

Just wanted to chime in here and say that I had this same exact problem, and this same exact solution fixed it for me. And the weird thing is that I definitely had 5200 stuff working previously. This problem only just started happening for me. Very weird.

It doesn't.

Atari 5200 controllers aren't implemented at all. There is no analog input into the system.
If you use something with analog, it's converted to digital first, which is why so many games don't work properly (Super Breakout, Missile Command, etc)

Basically it's an Atari 800 emulator (Which had digital 2600-style joysticks and a keyboard) with some 5200 stuff slapped-on.

If you have a keyboard attached, Numbers work from the keyboard. For instance, LEO in countermeasure is 123.

@mitu Ah - thanks for this. Doesnt look like it is going to implemented any time soon

lr-atari800 issues are almost always challenges with quirks of the original hardware, especially the fact that there are many versions. This is where all the things like cart autodetect for 5200, dealing with alternate versions of the OS, dealing with BASIC or not, etc, all come from. You actually run into many of these on the actual original hardware too (the infamous "Translator disk" for example).

Basic stuff like controls is now pretty sorted, as of last year, except for the 5200's analog stick in a small handful of games.

This isn't to say that there aren't some emu issues -- there definitely are, especially with the slightly older version of the mu that Retroarch uses.

Things like Atari 5200 cart autodetect don't work reliably because the person who coded it originally tied the autodetect table to filename, for example. But given that there are many alternate dumps of ROMs with and without headers, even a checksoum solution would need to be pretty extensive.

I strongly suggest people who are interested in Atari 8 bit emulation take a look at the guides in my signature, and in particular use the script I wrote. It makes most everything pretty seamless on the computers, and walks you through building a 5200 library that just loads without fiddling with anything.

@Thorr69 Thank you so much!

Happy to help. =)

@PCKid The .cfg files don't go in the ROM folders. Remove the /home/pi/.atari800.cfg file, make sure you've copied the right BIOS files and then start a game.
