I know there are projects like batocera for example but i want something i cant transfer from one device to another and just boot it up from my last save. Like i want it to work portable with various linux desktops os’s without the need to boot into a emulation os?
Does this make sense? if so how may i do it as a newcomer? What would you advise?


You want a live boot USB stick with multiple distros? Or just one distro? I think multiple live distros on a single stick would be hard.
If you just want to test multiple distros you can use Ventoy, but I don’t know if you can get it to retain data, it’s really just for OS installers.
A live boot of a single distro should be easy, but I don’t know which ones are good for that.
I’m not quite sure but i guess i need 1 ditsro because i fear more than that would be annoying? but is batercera the best choice or are there others? Sorry im really bad with wording and explaining things.
Batocera is great but I don’t think it has a regular desktop environment. So you couldn’t like browse the internet or use Steam.
If you use a different distro I think EmuDeck will give you the same emulators with the same frontend
