I spent two or three hours last night trying to get the MyM launcher to open on the SteamDeck, has anyone had any luck with this?
Hello Sinned42, Unfortunately. they use a custom Linux OS and it's clearly not standard. You'll need to take any issues up with Valve directly. We might be able to tell you what Libraries and such are required but that's about it. Note: The MyM Launcher is actually based on the open source SKLauncher. You should be able to find plenty of info on that online. Let us know if we can be of any actual assistance, HanoverFist69
