Yet another nds-bootstrap forwarder. Runs from 3DS-mode!

Yet Another nds-bootstrap Forwarder

YANBF (Yet Another nds-bootstrap Forwarder) is a forwarder structure for nds-bootstrap.

Features:

• "forwarders" are referred to placeholder icons that will shortcut to a particular application (in this case, nds-bootstrap)
  • Skip the second menu and just directly launch
• Launches from 3DS-mode.
  • The other implementation by @RocketRobz and @Olmectron, https://gbatemp.net/threads/nds-forwarder-cias-for-your-home-menu.426174/, is DSiWare, which means you are limited to only 40 titles. This works great on the DSi, it does not work great on the 3DS.
  • This means you can now install as many icons as you want until you max out the HOME menu icon space!

How it works:

• A pre-existing forwarder template exists: https://gbatemp.net/threads/nds-forwarder-cias-for-your-home-menu.426174/
  • This uses a DSiWare template, copies the icon and title and the ROM path, and then installed as a CIA. The CIA, when launched, will boot sdcard.nds which will do all the nds-bootstrap setup.
  • I instead opted to create an sdcard.nds bootloader, and then a 3DS-mode app that launches said bootloader
    • you can't launch .nds files from 3DS-mode. So a bootloader is required.
    • the bootloader does the same thing as the DSiWare template, in actuality

How to use:

1. Install Python 3 for your PC: http://python.org/downloads
2. Go to https://github.com/lifehackerhansol/YANBF/releases, and download the appropriate zip file for your PC OS
3. Go to https://github.com/RocketRobz/NTR_Forwarder/releases, and download the zip file that is not the source code
4. Extract the zip files
5. From the DS Game Forwarder Pack, copy everything in the for SD card root folder to your SD card root
6. From YANBF, copy bootstrap.cia to your SD card root
7. Download the latest TWiLight Menu++ version here. Only get the 3DS.7z file.
8. In the 7z file, go to _nds, TWiLightMenu, and extras.
9. Drag the apfix.pck and widescreen.pck file to sd:/_nds/ntr-forwarder/.
10. Open a terminal or command prompt and cd inside the generator folder
11. Run pip install -r requirements.txt
12. Run python3 generator.py
    • Make sure to replace with the full path to your ROM
    • this ROM MUST BE ON YOUR SD CARD! It will fail to generate properly otherwise!
13. An output.cia will be generated. Copy this to your SD card
14. Boot your 3DS and install both CIAs using FBI

Updating files:

Using Universal-Updater

1. Open Universal-Updater on your 3DS
   • You can download it here: https://github.com/Universal-Team/Universal-Updater/releases
2. Navigate to YANBF, then install the YANBF Forwarder Pack

Manually

1. Re-follow steps 2-9 in the "How to use" section

To build:

1. edit romFS:/path.txt to any file path in sd:/. Do NOT end with newline, this kills it.
2. run make dist
3. install both CIAs
4. voila

Current issues:
