You can run Pokesav on Ubuntu with WINE. WINE will also allow you to run other Windows programs on a Linux computer.

Assuming you have Pokesav already downloaded... Press OPEN, find your save game... (I think this is only for flashcart users...) And then you can edit it to your heart's content... Or to the Pokesav's content, actually. The pokesav for HGSS is only ver. 0.03, afterall. Anyway, there are buttons you still can't press. They don't work. If you want to try anyway, use Windows Enabler. (Google that.)
NOTE: YOU NEED ACTION REPLAY TO USE POKESAV CORRECTLY First open action replay code manager. Once open, drag the cheats you made with pokesav to the box. YOU MAY ALSO NEED TO MAKE A NEW CODE, AND COPY AND PASTE THE POKESAV CODE THERE. Once done, simply activate action replay on your ds, activate the pokesav code, and Voila! Your done!!!
Yes pokesav works on r4i
