@martinfr said in RPi 1 Model B only reports 256MB RAM under RetroPie:
To my surprise, the OS only reports 256MB of memory (checked through ssh).
Is that expected? If not, how can I tell it to use the full 512MB?
I think so - the rest of the memory may be reserved for the GPU, since it's used by both the front-end (EmulationStation) and the emulators.
