@wareagle18 You can copy/paste the relevant section of your key file, if you’re tech savvy. If not so much … I recommend Alternative Launcher.

(Expect an update to AL soon, but I hear v2.0 still works ok for 4.36.)

NB: if you have multiple devices with hats… there are some extra cfg steps needed. But I think AL handles that for you…
