RetroDECK got a lot bigger and better for emulation on Steam Deck

RetroDECK is just one of the ways you can set up your Steam Deck for emulation and their team recently put up a rather great sounding upgrade in v0.7.0b. During the Beta period their focus is on the Steam Deck but it will eventually expand fully onto desktop Linux too. Technically it works on desktop Linux but they say "the user experience might not be that great it could contain desktop specific bugs and other issues".

Giving you one of the easiest ways to get going it integrates with EmulationStation Desktop Edition (ES-DE), so you get a nice beginner-friendly and pretty good looking interface with everything all in one.

Just some of what's new inside RetroDECK v0.7.0b include:

• New controller layout, that unifies hotkeys for all emulators where possible.
• New system folder layout to make handing modding easier.
• Their own configurator is now integrated inside ES-DE. Plus lots of upgrades to their configurator.
• Updates ES-DE to the latest version.
• Updates RetroArch and their emulator cores to latest versions.
• Updates various other standalone emulators to their latest versions.
• Adds Wii U support from CEMU.
• Experimental multi-user support.
• RetroDECK auto updates on launch (can be turned off).

You can install it directly from the Discover software centre in desktop mode, since it's available as a Flatpak on Flathub.
