I have searched for this already and can't find quite the right thing I need.

I currently have a docked steam deck with an external ssd booting into windows with all my emulators and games set up they way I like them, this obviously works great having a mouse, keyboard and controller plugged it all the time.

However I would like to make this portable.

Is there a way (I'm assuming with an sd card) to have everything how it is now except without the dock?

Can I use the deck to control windows without any other setup? Is it as simple as cloning the drive onto a card and booting from that or am I missing somthing. What other problems have I not thought about?

I've used emudeck in the past but don't really get on with it much.

Thanks for any help
