Hi,
So when i use your method.. saves, roms, bioses, will be on that portable HD?

Hi, i have recalbox on ext. hdd, and it is possible to make it portable between two or more computers?

Recalbox is properly working(booting) only on one pc, after fresh install via raspberry pi imager.

When i take recalbox from PC1 and connected it to PC2, i got stuck on black screen after playing intro videos..

And when i want put recalbox back to PC1, i also got stuck on BS here too, and i must format hdd and make fresh install again..

im getting errors in recalbox.log:

Connected screen(s) / Max resolution / Fallback resolution lower than FullHD:
  eDP-1;1920x1080;1920x1080
Prefered screen HDMI-0 disconnected, fallback to first connected screen eDP-1
Force selected output eDP-1 to 1920x1080, disable others
xrandr --output eDP-1 --mode 1920x1080

PC1: Desktop, Nvidia RTX3090, AMD ryzen 9 5950x...
PC2: Laptop, Lenovo yoga, Intel cpu-integrated GPU only.

Is there problems with video drivers - can be installed drivers for both computers?

Thanks for reply.
