I'm Fabrice, the CM of Recalbox OS, the Retrogaming system
We are working hard (and for free...) to make Recalbox compatible with different Odroid cards (Odroid XU4, Odroid XU4Q, Odroid XU4 OGST Case, Odroid Go Advance, Odroid Go Super), and this, since 2017.
However, since that date (4 YEARS!!), HardKernel has never wanted to answer any of our many emails...
Is there a problem?
Why this silence?
Why don't you want to work with us?
All our team really appreciate your products, and we could do so much more, but... your silence is just discouraging.
You have my email in my profile, feel free to FINALLY answer me.

Have a nice day!
