Can I take extracted data and rebuild it?

[takeoaol]

I want to make a program the emulates Nintendo Zone. But I need to know how to modify a Streetpass file. It’s pretty simple to work with an extracted file but I don’t know how to recompile it.

This tool doesn't support rebuilding the save. You need to use https://github.com/wwylele/save3ds for it

What do I need to do in order to extract and recompile Streetpass data using save3ds?

[wwylele]

If I remember correctly, Streetpass data is a system/NAND save, which means you will need

• a mounted/extracted NAND (https://github.com/ihaveamac/ninfs can help with it)
• bootrom (boot9)
• The ID of the particular save. Should be somewhere on 3dbrew or maybe you already know

Thank you

I tried using ninfs to mount my nand.bin but it didn't help me get to my nand root.

Please open issue in ninfs / contact its owner for helping with ninfs

I used this command:
save3ds_fuse.exe "C:\mountfolder" --nandsave 0010026 --extract --boot9 "C:\boot9folder\boot9.bin" --nand "F:"

I got this error:
ERROR - Host IO error: Os { code: 123, kind: Other, message: "The filename, directory name, or volume label syntax is incorrect." }
IO error from host file system: Os { code: 123, kind: Other, message: "The filename, directory name, or volume label syntax is incorrect." }
Error: IO(Os { code: 123, kind: Other, message: "The filename, directory name, or volume label syntax is incorrect." })

What am I doing wrong?
