@kacpergards said in PiTFT 3.5" Rpi4 and Retropie not working.:

As of now I have flashed the latest Retropie, which works on my HDMI display, done the adafruit easy installation steps, which works. But instead of emulationstation running, I get the error message "failed to add service - already in use".

Hm, let me guess - the installer removed the KMS overlay from config.txt and now there's no GPU driver for the Pi. Post your config.txt.

@clyde Also, that different emulators for the same system can require different bios file names/versions. (as is the case with lr-genesisplusgx and lr-picodrive)

I may have forgotten to mention but I've noticed that when doing a initial clean install of RetropIe 4.7 I noticed that with my 8BitDo controllers that there is a bug that does not allow me to configure the Right Trigger and Left Trigger . It does show up as a Xbox 360 controller, I had fixed that input by updating Retropie to current 4.7.11 and redoing the configuration.

@kronos Yes. I don't know if it's completely out of beta for the Pi 4 yet, but the procedure is decribed here. And you'll need some sort of USB->SATA converter of course or simply an external USB HDD/SSD.

@mitu its like a white screen of death

@Chapster5 Thanks for sharing your solution. 👍

@cyperghost
Overclockings - No boot. cfg, nothing special
Themes - only the official and themas installer.
Easyhax - scripts only. Nothing that creates a fork
Bios - I believe that in this part I really made a mistake

Well I'm trying to delete the topic, but he accuses that I can not have answers in it. So since no one liked it, I'm grateful if any adm help me by deleting it for me.

No further.

@mitu definitely allwinner. Says it right in the name, they are all winners
