Hacking Is there a way to build NSP?

[johhnydamage]

Is there a way to convert the exefs and romfs.bin into a nsp file? I've got a few .nsp files from here and just used devtools to install to the system memory. Is there a way to convert the folders into that simply?

Everything I'm finding is pretty confusing or has private Discord links.

Thanks. I tried that earlier and can't get it to work. I drag the file and folder onto the Python file, it asks me to name the file, and that's it. I don't see it again.

Step 1) Get Python. You can find it by googling "python".
Step 2) Open a cmd. If you don't understand this, do windows key + r, type cmd and hit enter, or you can search for cmd.
Step 3) Move the exefs and romfs into the same folder as the .py file.
Step 4) Right click on the address bar in the file explorer and hit "Edit address" then hit Control + A, then Control + C.
Step 5) Go into the cmd and type "cd " (with a space after "cd") then right click on the terminal window. If you see a right click menu pop up hit paste.
Step 6) Hit enter.
Step 7) Type "python (name of python file) (romfs) (exefs)"
Step 8) If you're having any issues with what the script produces, reply to that thread with your issue and explain exactly what you did. If you have an issue with even producing a file, you should probably reply to this threat with the steps you went through.

Can you help me ?

is your romfs file called "romfs" ?
you need to put the real filenames. maybe "romfs.bin" ?

same for exefs.

the "provided command" is the example, you need to replace each part with proper file and path.

python <filename of python file> <filename of romfs> <filename of exefs>

real command is :

nspBuild.py <file 1> [<file n...>]

you can also drag/drop all your files directly on the .py file, if your system recognize it as launchable python3 extension. But it might create your file in another working directory.

romfs is a folder, not file. Can you see it ?

 

[Cyan]

ohh, sorry then
My bad.

the command line was written as if it was jokers to replace.
but, the official thread mention "drop the files to pack", and says "file1, file2, file...", not folders.

maybe you need to first pack the folders to files using proper packing tools, probably with keys and certs? romfs folder into a romfs.bin
maybe hactool has this option?

 

[loiuyt1207]

Can you guide "pack" to me Like romfs.bin or main.romfs

 

[Cyan]

no idea, never had to do it.
probably hactool, if not someone else will help you.
