@muldjord hey! is there any way to scarp systems like neogeo cd and naomi and atomiswave ' if not can u please add support for themes platforms i try to scrape naomi using -p arcade but not luck for almost 80% of my roms .

Re-install the retropiemenu package from the core package section.

@roslof thanks!

ROM version/Emulator version mismatch. Make sure the rom set you are using is right set for the emulator you choose to use.

@mitu OK sorry, i though there was something else to add, thanks! :)

There's on option in EmulationStation to show hidden files or not. By default it's OFF, but you can turn it on to show the . folders and/or files.

Right after I wrote the post, I hosted a Super Mario Kart game and played two complete tournaments against a stranger. So at least I know it works from "host" side of things, which I believe doesn't require actually downloading the databases or scanning rom folders. I'll try now to scan some more rom folders and see if I can join games created by someone else. I'll report back. Anyway, I believe that the whole process could be much more simple. Apparently it works from a technical perspective, but the user experience is terrible and not at all user friendly. Update: I was unable to join any games using the lobby system. Aparently Retroarch has no idea where to find the roms and the cores, even after scanning the directories, so I couldn't start any game. I tried to follow the instructions posted here, but they seem to be outdated and no longer apply. Hosting the game was fine, though, and a friend could join and play using a windows retroarch client.

It works, brilliant job thank you!

If by flash driver you mean an USB based drive, then yes. You can store your roms on a separate flash drive (as shown here) or you can install your entire OS on a flash drive - as detailed here, though you'll still need a sdcard to program the Pi first and this method is not yet supported on the new Pi4 model.

@Retroboii said in [HELP] After Retropie Update I cannot login: they dont say what type of file it needs to be (txt, DTB ?) How about no type ? You can create a file with no extension or you can add a .txt extension to the file (ssh.txt).

@KN4THX The problem it's not the hotkey, a lot of NES games use the select button for doing things in game. I'm a medium-skilled developer, with some guidance on the retropie bluetooth scripts and stack I could write myself a script which does in background the pairing procedure again, at least with one model, the SN30. If someone is willing to help or pointing me to who ask questions to, i'll be happy to try to write then publish such script.

You can execute those commands automatically when RetroPie starts by adding them to the /opt/retropie/configs/all/autostart.sh file. Edit the file (using nano from the command like) and add the commands before the line that starts EmulationStation.

Glad it worked out ! NOTE: I added some code blocks around the scripts code so it's easier to see and (maybe) copy&paste for future users.

@mitu Thanks, that works

@Toad That worked, perfectly. Thank you!

@bombers821 it is illegal to sell retropie especially with roms already included. 3rd party images are not supported here. If you would like support here you will need to download the official supported image (https://retropie.org.uk/download/). If you want support for you're current image you'll need to ask the person who sold it to you for help.

Ah, so it's not the RetroPie system that you cannot see, it's the EmulationStation menu. Did you, by any chance, switched EmulationStation to Kid mode ?

Fantastic! Thank you to both of you for your responses. AARM is a great tool! Exactly what I was looking for.
