How can I keep my saved game? Help!

[Lord Windos]

It will be enough to place the save file found in C:\users\<Username>\Saved Games\Pokemon_Uranium onto an USB flashdrive. That way you can reuse it on any other Computer, no loss in Game progress.

So, you mean I must copy the save file in that folder... and when I use new computer, I must download Pokemon Uranium first, then go to same place (I mean... C:\users\<Username>\Saved Games\Pokemon_Uranium)... and copy the old save file into it, right?
(I just a kid, so sorry for bad English, hope you will understand)
(Anyway, thank you for answer me, I think it quite helpful)

Correct, mate! Follow those steps, and you should have your old save ready to play in no time at all!
