extracting .app files?

[Sukiyo]

I'm trying to extract the .app files of the recently found 2010 E3 tech demos, but I just can't figure out how to do it, does anyone know how to extract them? thanks!

Due to these having slightly earlier formats you have to use a few different tools.

The original ctrtool works to extract the NCCH files (the .app): https://github.com/3DSGuy/Project_CTR/releases/tag/ctrtool-v1.2.1

The RomFS is a different format (ROFS) than the final version. Use this instead to extract its contents: https://github.com/PabloMK7/rofs_dumper

ctrtool --romfs=rofs.bin file.app
rofs_dump rofs.bin rofs

rofs_dump rofs.bin rofs

Output: "File is not ROFS" ??? This is my input: "C:\Users\username\Downloads\rofs_dump.exe rofs.bin C:\Users\username\Downloads\sk" I am trying to rip models from "Senran Kagura - Shoujo-tachi no Shinei (Japan)" .3ds file?

They are referring to ROMFS, not (.3DS) files.

in my "rofs.bin" part I am referring to the file and the directory after is where it will be outputted? Am I correct?

rofs_dump is for pre-release/prototype (e.g. 2010) files, not actual released software starting with 2011. You can use ctrtool to extract the romfs for most software.
