Really I meant this video
Why are you wanting something like this anyways?The thing is I need a modified DSi NAND Dump (In which I don't have a DSi and or a DSi NAND Dump) for the process and it will leave it with 2 files nand.bin and nand.bin.sha1 they say to put the files in the TWLN partition. In the shared1 folder you just paste everything and you are done.
Go and purchase a dsi from somewhere. You are going to screw your 3ds since you have no clue on what you are doing.Because 1. I don't have a Nintendo DSi and 2. I want to go nostalgic and use DSi Settings. But there is a downside if you press data management in DSi Settings on 3DS then the TWLN Partition corrupts.
I'm late but it's possible now :
