@dfelice81 Usually they're created per system, since each system has it's own native resolution and you need to make sure the overlay doesn't obscure the game's video output.

Go to new fourm called Retro Pie Backup to new sd card

I found the issue if anyone else has the same problem. I had saved a core config in each of the emulators which caused it to be set in what ever resolution it was in at the time. Configs are stored in opt/retropie/configs/all/retroarch/config/all/retroarch/config/(name of emulator). I deleted them and re set them up in 720p.

I installed almost all packages for Retro Pie in Ubuntu 20.04 LTS onnRaspberry Pi 4 but couldn't get lib-raspberrypi-dev
It's for mad/intel 64 bit PC's

There’s some info here: https://github.com/RetroPie/RetroPie-Setup/issues/2961

I think RetroPie has been set up to default to these emulators if you have a RPi4.

Hostname works but only with Ethernet
Tried without Ethernet just continues trying to connect
I usedhostname retropie

The display order is they're entered in es_systems.cfg file. If you want to re-order them, move the <system>..</system> entries in the configuration file.

anyone know of a way to convert sharp x1 .tap files to a format that lr-x1 can load? this seems to be a pretty obscure question.

Hello @mitu

Thank you very much for your hint about KMS in the config.txt file.
I really didn't paid attention to this.
It was really commented, I don't know why. I didn't ever edit this file.
Now the installation has finished successfully.

The solution was really uncomment the two lines below regarding KMS dtoverlay into /boot/config.txt (and restart) :

[pi4] # Enable DRM VC4 V3D driver on top of the dispmanx display stack dtoverlay=vc4-fkms-v3d max_framebuffers=2 [all] dtoverlay=vc4-fkms-v3d start_x=0 gpu_mem=256 hdmi_enable_4kp60=1

Thank's a lot for your help. I hope this topic may help many other friends to enjoy Retropie.

Kind Regards.

@simpleethat I didn't think I could, but I just had to ask. Thanks for the reply! :)

@neurocrash Nevermind, it was supposed to be opened with the Hotkey+X button, but on the diagrams for controller buttons reverse the X and Y keys, so I had them mapped backwards.

@mitu that will lose the input config script trigger. To clear es controller config, there's an option in RetroPie-Setup in emulationstation configuration.

@neurocrash said in Can't enter RGUI menu anywhere:

The result is that the hotkey that works for me is Hotkey-Y, which is the same as the Hotkey-North button. When using this combination, all of the devices can open the RGUI menu.

The North button is the X button, not the Y (yes, the XBox controller is backwards).

Yay! @mitu you are awesome. Thank you!

It turns out that the GPi uses the "windowed" version of the settings, so I needed to add the following to /opt/retropie/configs/all/retroarch.cfg

menu_widget_scale_auto = "false" menu_widget_scale_factor_windowed = "2.75"

For what it's worth I had actually stumbled on this setting when messing around but I set the non-windowed value (because it's full screen... I assumed that meant it wasn't windowed) and when that didn't fix it I moved on.

Try installing the xpadneo [1] driver and re-do the configuration for the controller - pair it via Bluetooth and configure it in EmulationStation.

Back-up your ROMs/BIOS/Configs via file shares from you exiting Pi 3 installation - see https://retropie.org.uk/docs/Updating-RetroPie/#making-a-backup-option-2, then install/flash the new Pi 4 image on the SD card. After installation restore the files you backed up in the previous step using file shares to the same locations (BIOS/ROMS/configs).

It's always advisable to make a backup of your existing installation, but you already did this,
