Screen upside down

[hoenens]

Ok, in Raspbian i know the LCD_ rotate line in the config to fix it, but i am using berryboot now, can i change this here aswell.
Also when i boot into retropi, screen is now also upside down. How to fix this so the screen is always the right way?

Within raspbian now whan i wanna config the boot/config.txt when i open it in the terminal it's empty....

sudo nano /boot/config.txt

Make sure you have that first /

/boot/config.txt can be empty. In most cases the RPi will boot perfectly and the default configuration will "just work".

For lots of settings, the easiest way to set options in /boot/config.txt (and /boot/cmdline.txt) is with sudo raspi-config. Except in this case.

You can write a single line option into /boot/config.txt with
sudo sh -c 'echo "lcd_rotate=2" >> /boot/config.txt' if you don't like sudo nano.
