Backup the ROMs and BIOS folders, the \\retropie\configs\ folder - the emulationstation folder contains your collections and ES settings/own themes`. Here's a topic discussing this in detail - https://retropie.org.uk/forum/topic/16866/.

@BJRetro Yes everything works good! Thanks for the extra info on Naomi/Atomisware!!! Guilty Gear X 1.5 and Fist of the North Star works great.

@asici2 Yes, the feature is only available for lr-fbalpha. FBA is optimised for Capcom fighting games so lr-fbalpha is the recommended arcade emulator for the Street Fighter games. You will need to find a new romset as lr-fbalpha uses a different one to MAME. More info at: https://retropie.org.uk/docs/FinalBurn-Alpha/

@defenderdev Ok I'll give it a try thanks

In my case, it was because I registered the PS3 dualshok controls, using the xbox360 driver ... In emulationstation it works ... But in RetroArch it does not. The solution was: uninstall the xbox360 driver and re-activate the ps3 dualshock official driver, when rebooting ... Resigne the buttons in emulationstation, I recognized as ps3 dualshock command and I work the retroarch controls in all the emulators.

@orangewaffle Ok, reaching home, i got the information needed: Pi Model or other hardware: (B, B+, 2 B, 3, X86 PC etc..) 3 Model B+ Power Supply used: (If using a Pi) Samsung genuine adapter, 2A RetroPie Version Used (eg 3.6, 3.8.1, 4.1 - do not write latest): 4.3 Built From: (Pre made SD Image on RetroPie website, Berryboot, or on top of existing OS etc.. - please provide the filename of any image used) Pre made SD Image on RetroPie website, but i can't remember which one USB Devices connected: 2 Controller used: DragonRise Inc. Generic USB Joystick Error messages received: - Log found in /dev/shm/runcommand.log (if relevant): - Guide used: (Mention if you followed a guide) File: (File with issue - with FULL path): - Emulator: (Name of emulator - if applicable): can't say, because i can't get into emulator options (nothing happens if i press any button during game load) Attachment of config files: After replacing a 1A charger with a 2A one and giving the setup a one day rest, 7 out of 9 buttons work now, instead of 1. Top left button still does nothing, as well as the hotkey button. In the weekend i will try a clean install of the latest retropie image and keep this post updated.

I use a small wireless keyboard to set things up. I also stuffed a U-hid nano from Ultimarc into a 2600 console so the switches work for navigation. I used a similar USB adapter for the controllers. I think I used Stella and not LR-Stella to make it work with paddle controllers too.

@loonyboi Thanks! I wasn't sure if you meant to mirror the controls by ES' UI or at file system level by copying their config files. So if I understand you correctly, setting them up identically in ES does suffice.

I'm having the same problem where none of my controllers are working in game, however, I know what you're talking about, as I had that same thing (with the having to basically hold all the buttons to get it to open the remap screen) happen to me. Unfortunately, I have no idea what caused it, and I was only able to fix it by doing a clean install. If it's any consolation, since the install I haven't had that problem (just my current one where my controllers aren't working in game)
