Hi!
Here is the ISO for those that are making the DIY project by themselves using an Odroid H4.https://github.com/Playnix-io/playnix-os/releases
Playnix is going to be the brand I'll be using for my hobby hardware projects in the future so they don't affect EmuDeck in any way, EmuDeck is my main focus but I need some hobbies too :)I've created this Live CD ISO myself for this matter, you need to deploy it to an USB drive using a tool like Balena Etcher ( https://etcher.balena.io/#download-etcher ).Install the OS on your Odroid and then when you are in desktop mode click on the "Enable Gaming Mode" icon so Steam and all the other needed goodies are installed, after that you can use your Odroid like a SteamOS device with Gaming and Desktop mode like a Steam Deck.
PS: An Android APK sneak peek is coming soon :)
