      Pi Model or other hardware: 4B+
      RetroPie Version Used 4.6.5:
      Built From: Manual install on top of Raspbian
      USB Devices connected: None
      Controller used: None
      Error messages received: See log
      Verbose log (if relevant):
      Guide used: (Mention if you followed a guide) Official Manual install guide
      Attachment of config files: https://pastebin.com/j12prrnA

      See the log for details, but basically it can't install retroarch whenever I do the Basic Install.

        Did you modify the default config.txt from your Pi image ?

          @mitu I set the gpu_mem to 256, but I think that's it unless something else modified it. Here's the full file: https://pastebin.com/FpyhtXU1

            @Ninjinka That's not the default RPI image config.txt - did you install anything else ? The issue is that the vc4-fkms-v3d overlay is commented out and this disables the Pi4 GPU drivers. You need to enable it back to have a working RetroPie installation on the Pi4.

            If you're just starting with RetroPie or Raspbian, I recommend using the RetroPie image for installation. It's based on Raspbian Lite, so you still have Raspbian available.

              @mitu Yeah I installed this LCD driver, maybe that's the issue? http://www.lcdwiki.com/4inch_HDMI_Display-C#How_to_use_Raspbian.2FUbuntu_Mate.2FKali.2FRetropie_system I will try uncommenting the vc4-fkms-v3d. Thanks!

                Ok apparently there is a compatibility issue with the display driver, because if I uncomment that the display doesn't work. They have drivers that are compatible with Retropie on the Rpi3 but not the Rpi4 yet. I guess I'll reach out to them and see if they have a solution
