BootCtr - A simple boot manager for 3DS

Based on 3DS Homebrew Launcher code by Smealum. The original version is from mashers. This version removed some unused code used by Homebrew Launcher that isn't necessary in a simple bootloader, and added some interesting new features.

Any question can be done in the official topic in GBAtemp forum.

Features

• Supports both .3dsx files and binary payloads (for example, /Cakes.dat,
• /ReiNand.dat, /rxTools/sys/code.bin, etc.).
• Supports advanced features in .3dsx files, like network support.
• Boot delay, to increase the boot rate chance of CFWs like rxTools and CakesFW.
• Allows up-to 16+1 (16 using keys plus 1 default) homebrews in O3DS, up-to 22+1 homebrews in N3DS.
• Support for boot screens, including an ASCII art (default) or custom images in BGR format:

Installation

• (Optional, but recommended) Install HomeMenuHax and set up autoboot.
• Modify, according to your needs, the included boot_config.ini file.
• Copy both boot.3dsx and boot_config.ini to the root of your SD card.
• For splash screen, look inside splash folder for some ready to use .bin files (including source file/preview in .png format), or use the included img2bgr.sh script to convert your own images (or convert them using this site). Dont't forget to edit boot_config.ini to include splash_file option in the desired entry.

Usage

• Boot up your homebrew hax as usual.
• If you do nothing, then boot_default.3dsx (or anything that you setup in [DEFAULT] section) will be launched.
• If you want to load an alternative launcher, hold down a button (configured according your boot_config.ini) to boot it.

Compiling

First, clone this repository including the submodules:

$ git clone --recursive https://github.com/m45t3r/BootCtr.git

Compile a new binary using the included Makefile and devkitPro. If devkitPro is correctly installed all you need to do is:

$ make

And copy the new boot.3dsx file to your SD card. Do not forget to copy boot_config.ini too.

Alternatively you can run the command below too (needs zip and git installed):

$ make release

To generate a .zip file including all source code and auxiliary files, ready for distribution.

License

The original source code (Homebrew Launcher) does not have a proper license, and since this code is derived from it I can't simple change the license for something that I would like. The README.md from HBL says:

"Feel free to use code from hbmenu for your own projects, so long as you give credit to its original authors."

In the section below we give proper credits to everyone that helped creating this project. Of course, all of my modifications is distributed in a similar license, so go ahead and fork and do something interesting.

CakeBrah does not seem to have a proper license too. However, brahma uses a license similar to MIT (see README-brahma for details), and CakeBrah is a derived work so it should use a similar license.

inih is distributed under New BSD License, while libkhax (not used directly, however it is a dependency of CakeBrah) uses MIT license.
