Huh, changing that shouldn't have mattered, especially given that the game was originally NTSC! You might want to look at the script I wrote here: https://retropie.org.uk/forum/topic/22392/lr-atari800-5200-artifacting-basic-and-other-guidance/17 if you want to get hardcore on Atari800 emulation. Also might want my fixed build of the emulator, if you ever want to play anything that requires typing. https://retropie.org.uk/forum/topic/22460/fixed-ctrl-and-shift-on-lr-atari800

@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.

@Dwarfboysim Sorry, it's the other way around, I'm using lr-atari800 not atari800

@bkumanchik The k is because you have loaded a "k-file," which is a specially optimized variant disk format for faster loading. It's generally noted in the game filename, like Zombies (1983)(Bram)(US)[k-file].atr It's a bit odd that you are in BASIC and see it, usually it goes away once you are in the game and it tends to be on games that are machine language. For those sorts of games, you want to disable BASIC. If your goal is to do some BASIC programming, I suggest finding a DOS 2.5 system disk, and booting to that with BASIC enabled. If your goal is to load a game and you are getting dumped to BASIC, I suggest disabling BASIC in the RGUI menu (Select-X, Options, set BASIC to disabled). I just posted a giant thread explaining most everything about Atari 8-bit emulation in Retropie here: https://retropie.org.uk/forum/topic/22392/lr-atari800-5200-artifacting-basic-and-other-guidance

@rkoster OK, thanks!

@rkoster wow this is great. Thanks. Haven’t read it through completely yet as I’m away on business. But what about games like, one of my favourites, Spelunker that require some keyboard commands like space bar for phantom blaster and keys to launch flares and dynamite. Can that be set on say my shanwan ps3 controller to use it? Basically all others work fine as Atari Joystick. I do have a Logitech wireless keyboard with mouse pad so I could use that in front of me as well for extra commands. But would be fiddly if could all be done with the controller.

@PolarBear123 BIOS files, just like ROMs, are copyrighted assets - they're not distributed with RetroPie and links and request for such items are not within the forum rules.

Depending on game, you may need to change the machine - some will work only on 400/800, 800XL (64) or 130 XE. Other thing that often helps is to "enable BASIC on boot" in options. Of course you need to have all the appropriate bioses in the right place/detected too.

@annomatik Where does it chance ?

@drmaxwell Are you using RetroPie ? Please give more details about your setup - https://retropie.org.uk/forum/topic/3/read-this-first.

@paulmdickey We really need to know more information about your setup. The required info is detailed at https://retropie.org.uk/forum/topic/3/read-this-first Take special care to note if you're using the Atari800 emulator, or lr-atari800.

I was struggling with the config file saving using lr-atari800. I uninstalled it and installed the regular atari800 emulator. Now the config file works. I also had to set the display to something I could see first. There are presets for the display that work fine.

Try quitting Retroarch after you change to Atari 800XL (don't go back to emulated system, just quit RetroArch and it will exit to ES, then start game again and it should work). I believe RA saves configs on exit. If this doesn't work then change to 800XL (or better set it to 130XE as it has 128kB of RAM) and select save core override in RA.

@davidgrohl Learn how to use SFTP or Samba-Shares. https://retropie.org.uk/docs/Transferring-Roms/#sftp https://retropie.org.uk/docs/Transferring-Roms/#samba-shares If using SFTP, go to /opt/retropie/configs/all/atari5200/retroarch.cfg, or if using Samba-Shares, go to configs/all/atari5200/retroarch.cfg. Add core_options_path = "/opt/retropie/configs/atari5200/retroarch-core-options.cfg" to the retroarch.cfg above the #include "/opt/retropie/configs/all/retroarch.cfg" line.

@mediamogul Reinstall did the trick, ta :) Still can't figure what the heck to do with XEX files, mind you.

@gpmcty You probably figured this out a long time ago but the config file is in the /opt/retropie/configs/atari800/ folder.

Hi everybody, I finally found the reason. Unfortunately I MOVED the ATARI 800 games from one installation to another. Though there were no roms present in the Atari800 the emulator did not show up in emulationstation.

@Seeker Is there anyway I can download them and place them somewhere so it can install? There's always a way, but I feel that it's a bit more than I can relay in a series of forum posts. If this is something you want to explore, you should do some reading about how software is installed on Linux in general, which can then be applied to RetroPie. That kind of research and application is most certainly rewarding, but for simplicity sake, I'd recommend just getting a WiFi dongle.
