@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.

You've posted your topic yesterday and you've bumped it twice - it's rude and it's bad forum etiquette, please don't do that.

@mitu It works now. Thanks alot!

Hello,

Can anyone please help or give some guidance on the problem above?

Thanks in advance!

@t-prime
So, while I haven't begun with setting up my project, i still want to ask to be sure, as I'm quite new to all of this... (°_°). To keep the "fully working" hdmi, I can still follow the tutorial by adafruit (https://learn.adafruit.com/running-opengl-based-games-and-emulators-on-adafruit-pitft-displays/pitft-setup) and use their script, but I'll have to answer NO once I'm asked as you described and change the .txt file, right?

@dhlee20 said in How to load Retropie games in full screen with no black parts...:

I bought a 2.8 inch 320x240 PiTFT display for the PiGRRL 2 project from Adafruit.

When I load GBA games in Retropie, there are about 5mm of distance from the end of the screen in both sides.

Can you guys tell me how to load the game in full screen? (whole screen with no black parts)

<config.txt settings>

#framebuffer_width=320
#framebuffer_height=240

#sdtv_mode=2
#sdtv_aspect=3

Remove the # symbol from config.txt in these lines:

#framebuffer_width=320
#framebuffer_height=240

See if that helps.
