Stuff 3DS

A collection of misc tools and godmode9 script for the 3DS.

User guide

nds-hb-menu:

Meant as an easy way to install a twl hb environment from a cia on 3ds.
Since titleDB doesn't allow cias with srls as their content section, this app embeds bootstrap.cia in its romfs, which it installs upon boot and copies boot.nds to sd root as well. Install from FBI titleDB under Stuff.

SUDOject:

Godmode9 script that can install/uninstall sudokuhax to DSinternet or DSdownload play.
Download USA.zip from plailect's guide (magnet links) and extract game_usa.app and public_usa.sav to sdmc:/gm9/in/SUDOject/<here>
DSdownload (00000000.app) and DSinternet (00000002.app) should be dumped to that directory upon boot assuming they aren't modified.
Should work with USA, EUR, JPN, and KOR 3ds's.
Should work with clean firm which is some nice insurance.

3DS_NVRAMtool:

Dumps nvram.bin to sd card and writes it to the 3ds's spi wifi flash. Also fixes broken crc16's on the
6 wifi settings sections and DS profile 1 and 2 so you won't have to overwrite any settings, unlike NVRAM Flash Manager.

screencapBinMaker.py:

This program creates the .BIN files that 3ds home menu generates when taking screenshots.

ivsdec.py:

ftpd_ctrnand.cia:

ftp's into ctrnand. Not recommended for everyday users or morons because of the obvious brick risk.
Only use this with ntrboot or hardmod as a backup.
