Thanks @mitu. It works now for the custom lists.

About the joystick selection tool permission issue, I'm waiting for a new Xinmo interface shipment before pushing further. Once I have it I will try again. I have a 4 player board on my arcade. I would need longer GPIO cables to follow my initial plan to connect player 3 and 4 on one Xinmo, but those cables come from China and seem to be out of stock due to the disruption of global value chains.

I hope that the Joystick selection tool will allow to connect P1 and P3 on one Xinmo, P2 and P4 on the other (considering cable length), then reallocating the players with the tool. If I can make it work.

@mitu awesome, that did the trick! I now have RetroPie, SteamLink, and Linux desktop all running on Raspberry Pi :)

@retropieuser555 the long and short of it is that framebuffer emulation is required for many games to function properly. There is a performance hit for having it on, but the alternative is that you'll have issues such as yours.

SOLVED

All I had to do was delete my recently uploaded splash screens through samba and reboot.. I guess you need to save video splash screen files a certain (unknown) way before you transfer

@mitu I wanted to circle back, you were right. In the terminal, I typed df -h / this got me the info on the SD card. So, that resulted in 118gb Space, 113gb used, 0 Space available, 100% used up.

I thought this was odd, my SD card should be close to 128gb. Anyways, I deleted a bunch of games, etc and ran the same command and got the following:

118gb space, 103gb used, 10gb space avail., used 92%

So like I said, you were right!

Thanks!

The finally solution for me was manage the relationship 1:1, one speaker with one dongle (USB). For spread the sound on all speaker i used an virtual audio card with "paprefs". Maybe we'll see this skills on new Bluetooth versions.

@MDtar7 Im running out of ideas, but try enabling SMB 1.0 support on your PC.
Its in Control Panel, Programs and Features, Turn Windows Feature On or Off and select SMB 1.0/CIFS File Sharing Support. Restart your computer and try it again.

Use raspi-config and configure the system to auto-login to the console. If EmulationStation doesn't start automatically after a reboot, then use the setup script to enable the autostart of EmulationStation - see https://retropie.org.uk/docs/FAQ/#how-do-i-boot-to-the-desktop-or-kodi.

Is there any reason you're not using the RetroPie image directly ?

Hey thanks guys this really works with lr-vice!

I can map several keys to my retropad (I use a PS3 sisaxis), including the joystick swap and the virtual keyboard. I mapped Y,N,1,2,return,space,F!. Here is my configuration as an example (in the retroarch options menu):

show mapping options: on
hotkey toggle virtual: keyboard retrok_f11
hotkey switch joyports: retrok_rshift
retropad select: toggle vkbd
retropad start: retrok_rshift
retropad b: --- (=fire)
retropad a: retrok_return
retropad y: retrok_space
retropad x: retrok_f1
retropad L: retrok_1
retropad R: retrok_y
retropad L2: retrok_2
retropad R2: retrok_n

Also, if you have trouble inputting some letters in text-based games (like A or S), you must chose "physical keyboard pass-through: on" and everything will be OK.

The mesa-drm package should not be needed for a RPI3b+ installation.
Please add more info about your setup - as detailed in https://retropie.org.uk/forum/topic/3/read-this-first.

It seems you do need to install something - see the manual:

Once connected and booted up, you can navigate to the terminal to install the required
gpio drivers.
In RetroPie, you can do this by pressing the Ctrl-Alt and F4 key; this changes view to a
virtual terminal window, which you can run ‘emulationstation’ to go back to
RetroPie.
...

It looks like you need to install GPIONext, a GPIO user driver to make the gamepad(s) work.

As @sirhenrythe5th said
3rd party images
are not supported

I don't know the author. I am planning to use this build I have as a temporary until I get my keyboard in the mail. BTW how are you always on here? You give replies 24/7! XD

@mitu I got it working by setting the emulator to "psx-rearmed" instead of "Ir-psx-rearmed". I want to double check if this is a safe way to fixing the problem

Hm. Still at a loss. Do I have to save the game config to make it work? I would like to make a working configuration on the fly and only save it when it works. Also "User 1 Device Type" - I believe this should stay RetroPad? "User 1 Analog To Digital" - should I fiddle around with that? "User 1 Steering" is set to "Left Analog X" - which sounds reasonable, but does not work...

@VictimRLSH Hm, a quick test shows it's not working at runtime (i.e. without rebooting the device). Maybe fiddling with tvservice would allow this - I'll have a to check more.

thank you
its greatly apreciated !

@sushisan I do agree with that. The code that fails was added later and I guess wasn't tested on older cmake. We can bump the cmake version but I don't mind if someone wants to make it work on older cmake too so long as it's easily maintainable. Eg Not having to adjusting the JSON cmake files if we upgrade that component to keep compatibility. Easier just to require a newer cmake.

@BuZz
I write the solution for my case. Maybe it could help someone

Pi4 model b
access point: TP-LINK RE450

Retropie, any version for some strange reason does not connect to the access point.

SOLUTION: I had to install an OPEN-WRT custom firmware on the access point.

Once rebooted and configured, everything works.

The strange thing, that the first time, with the firmware stock was connected perfectly, then you can not.
