351ELEC 2.0 Released: The Ultimate “Plug and Play” Firmware for RG351 Devices

Last Updated: 23FEB2021

When it comes to custom firmware options for the RG351 devices, 351ELEC is a masterclass in curation and user friendliness. While I adore ArkOS for how easy it is to tinker with the device and firmware, 351ELEC is more suited to those who just want to jump into some games without having to do a lot of tweaking.

Lucky for us, 351ELEC 2.0 is now available, and it has hundreds (over 275, to be more precise) of new tweaks under the hood and in the user experience. Check out the video for my full breakdown, and also see the notes below for links to some of the things I mention in the video.

  1. Any idea why PS1 games show up as a massive list and how to make it just one per disc?
    Example I have about 25 Destruction Derby in the games list but only one disc image for this game.
    It was the same on ArkOs and now on Emuelec so not sure how to fix this.


  2. Keep the files in one folder, and only boot the .cue file. The .bin folders are a section of the game or part of the soundtrack. You need all the files, but the .cue file is the starting point. Twisted Metal 4 is a good example. You’ve got soundtracks that are different for each level, so you have several .bin files. You start the .cue file and it’s going to start each level with it’s proper soundtrack in order. It stems from the British slang for being in line IE “get in the cue!”


  3. If you were to switch from ArkOS to 351ELEC would the game saves still work correctly? I am considering this switch due to this 2.0 update. ArkOS is a great platform but it can be a lot of things to remember when I am just looking for plug n play. TY!


    1. It’s a new flash, so you start from scratch. You can use a second SD card to save a headache, but a fresh flash means that everything is new. I’m currently re-flashing a second card to ArkOS because of some hiccups within the OS version I was using, and it’s really refreshing to have a second chance to perfect my system.


  4. I’m new to all this, and only flashed the old version a couple of weeks ago when I got my RG351M. How can I do this but still keep all my save states and things like PS1 saves that are saved to the ‘memory card’? Do I just do a new flash and tehn transfer all my ROMs over from the old card onto the new card and everything works fine?


  5. Following up with my question after doing some more digging on my own. Both firmwares handle game saves in the same manner (with the game file). I am not sure about save states however, since 351ELEC has a save states folder…that may be different. Haven’t tested moving the .srm files into that folder yet or just seeing how and where 351ELEC save save states, but that could work. I am loving the 351ELEC firmware so far, not having to change the screen ratio is great. I couldn’t figure out how to save it to the core with ArkOS even with the guides on this extensive site. Loving the themes downloader and the update checker. Great user experience.


  6. Can’t seem to get the frontend BGM to function on 351elec 2.0 with my 351p. I dumped a few mp3s into the BGM folder with the expectation that turning frontend music on would then cycle through the mp3s on the menu screen, and while it shows the notification for the track changing, it will not play the audio. Wondering how to get that sorted out because everything else is working wonderfully.


    1. you can convert the mp3 files online in the .ogg format.
      mp3 files are not supported at the moment, only .ogg and flac files.
