ROM Hack Extracting NDS from CIA

[AkitoTheHedgy]

Hello! I am just wondering if there is a way to extract an NDS (Or some sort of file) from a CIA file (3ds game format.) If you can, can you tell me how?
Thank you!
(also idk where to put this.)

NDS isn't in CIA format

Oh.

But I'm trying to extract the game files from the CIA game. Is there any way I can do that?

Yes there is a way

Yes there is a way

When I follow your link the description tells:

What you Need

• An encrypted 3DS|CIA|CXI file (It can either be a game, game's update, system application, but anyways not a DLC file nor a DSi Ware!)

So this tool can't be used to extract the NDS (DSi Ware). What else can we use?

Thank you!

I couldn't find extract.bin but

ctrtool --contents=contents the_DSiWare.cia

gave me some interresting file:

$ file contents.0000.[SNIPPED]
contents.0000.[SNIPPED]: Nintendo DS ROM image: "[SNIPPED]" ([SNIPPED], Rev.00) (multiboot)

So I changed the file name (and ofc the file extension, too) and TWiLight Menu++ loads it just fine.

It was a mistake, i meant extract.bat. Fixed it, thank you
Glad you got it to work!
