my N3DS XL was on a FW too high for anything other than Cubic Ninja and Ninjhax 2.5 when I bought it, so no. no Gateway. I believe I used FLsavetool. but how does it not work for you? doesn't anything show up in the folder when you try to dump the save, or do you try to open the wrong save file in the editor?
well on the first page it says to use the flsavetool, or fantasylife save tool. It doesn't say where I should put it, whether in the root sd card folder or the root homebrew folder, it does however have a txt file that says that it will focus the exdata dump tool by mr cheeze so it will target fantasy life extdata which is of course where my save files are. But the md on the download page for extdata dump tool doesn't say where to put the files we have to download, again the sd root folder or the homebrew root folder, or even if we have to use all the files.
The problem I have is that none of the download instructions are clear on where to put anything and only svdt shows when I run homebrew and then it doesn't work when I run it.
