To use a Switch controller wired, you have to install both of its drivers first:

After this, you must press ZL and ZR to pair it everytime. Working fine on a RPi3B+.

You purposely want to build a cab that can not play most games? 😯
Anyways you'll have to check the keys n the mame menu, i think by default you access that by holding start. you can also open it from the retroarch menu, you can not see it from within emulationstation like you're trying to do on the picture.
Start the game first.

What you're configuring is actually a keyboard - mapping GPIO pins to keys - so you can set the P2 inputs to whatever you want (as long as it's not conflicting with P1). The real configuration has to be done in the emulator and in EmulationStation you can have only one of the players configured to navigate and launch games.
I think there are a few arcade games that require P2 Coin input, so having just one coin input might pose some problem for those games.

See the Keyboard controllers doc page for additional details.

There are separate drivers that can interpret the GPIO input and simulate 2 gamepads - like mk_arcade_joystick. They require either a specific wiring schema or manually configuring the mapping with driver options.

You can add shortcuts to your gamelist that will start with an empty file, thus disabling the auto-loading. Some emulators already have a similar shortcut (+Start Amiberry, +Start Fuse), you can replicate the setup for others.

If you prefer working from the desktop, then you can leave RetroPie alone and just install the emulators manually on a Raspbian + Desktop image.

If you have a 4k TV, try setting the video resolution of your Raspberry Pi to 1080p - you can modify the /boot/config.txt file on the sdcard and set

hdmi_group=1 hdmi_mode=16

then reboot your Pi.

No, at the moment this is not implemented in EmulationStation, the videos are always read from the gamelist.

@mitu thanks mitu☺️

@yserra Thanks! I suspected as much.

@saucerman My pleasure. To mark this thread as solved, you could add a [Solved] in front of the title of your first post. To edit the post, click on the little three dots on the left and choose "Edit".

This is not required (in fact, alas, almost nobody does it), but just a common hint for potential helpers to know that their help isn't needed here anymore, since the forum software itself has no such feature. 😉

@alistairgd said in Wired XBox Controller works in menu but not in-game:

Now, it works for P1 in some games, but as P2 in other games.

Do you have any configuration overrides for the games where the configuration is not applied ? Try removing them. If that fails, give an example of such game and maybe provide a verbose log from running the game.

@mitu Finally got it working ok with your help (THANK YOU), full upgrade using Putty worked although my laptop crashed and corrupted the SD card at around 80% of update and had to reflash it and start all over again.

But copying the two files across, then updating via putty worked in short.

Thanks,
Tom

@mitu ok, i will do just that. i will have my old image restored, update the OS and retropie, then follow the instructions in the previous thread.

@mrnoholster what happened is you updated fb-neo which requires a new rom set. The old roms are not for newer versions.
FYI. Updating arcade emulators to newer versions is risky as there is no guarantee that the update will work with your roms. Don’t update them if you have a working set of games. Most roms may be fine in if you just go up to the next update, but if you keep updating, there will reach a point where fewer and fewer roms run.

@jimiretro Usually you get a message only on errors.
If the mount command worked, then check if the roms folder is populated, then start EmulatonStation.

@mitu

thanks, after a folder search i found it.

@quicksilver dont quote me on this, but yes i UPS will help level the spikes. a surge might, but i think the choke if there is one on a surge protector will not be that big compared to a UPS

@officerdibble

I found that by editing the config.txt file that corrects it.

I used sudo nano /boot/config.txt and removed the # in front of disable_overscan=1 to enable it.

@crush ... Ok testing complete. The powered hub will work with or without the adapter pulling power from the adapter if present.

--> Shutdown Pi.
--> Add USB hub *unpowered.
--> Add USB audio.
--> Bring back up.
Result: Same odd behavior with the controller etc. on different newer hub.

-->Shutdown Pi.
--> Plug in power adapter to USB hub.
--> Turn on.
Result: Everything works as expected.

So in my case it was a voltage issue with the X-Arcade and the USB audio being on the same USB hub.
