Why RIO
Not just a
game launcher.

Bold visuals
Pixel fonts, green and yellow, console animations, animated covers and a record player.
One library
RomM keeps the collection; the handheld browses and plays it.
Built for small screens

Your data, protected
Restorable save copies, transfer checks, card-use protection and clear failure messages.
RIO Pixel World
A pixel world,
out of the box.
RIO ships with its own original content: a theme song, a short film, a short story and a poster. Listen, watch and read from the first boot.
