I have a M3DS Real that I bought in Japan back in 2008. It's running Sakura and has a good amount of games on it. It's been in my gf's DS ever since I came back and I haven't really maintained it or kept the firmware up to date. I've recently got back into the flashcart scene and wanted to update this to the BEST firmware possible (do a complete reformat). I'm not sure about which would be best as this was bought from Japan (asian model) and was hoping the community could advise. Thanks again in advance.
