Reverse out the nitro developer kit from a game, so custom cart images can be created that can accesses ROM data just like a commercial game would do. To eliminate the need for DLDI patching when running from flash carts.
To be able to do this a ROM dump of a commercial game is needed. I decided to go with:
Tetris DS (NTR-ATRP-EUR)
MD5 340856a9c56cc6cb6cd0966b38f5624f
Use gnu md5sum to generate the MD5 sum.
Depends on devkitPro for cross compilation and creating NDS images. See: https://devkitpro.org/wiki/Getting_Started
Requires GNU make >= 4.3 See: https://www.gnu.org/software/make/
Your environment needs two variables to be defined in order to build the projects in the /src folder:
- TETRIS_DS_ROM: the location of the Tetris DS ROM dump
- NDK_DIR: the location of the src/nitro folder in this repo
See: How to export environment variables in linux.
The font used by the src/util project was found here: https://github.com/dhepper/font8x8

Use private function file section template to unclutter the modules. See template below.
/*========================= PRIVATE FUNCTIONS =================================
* The heuristic for 'private' functions is that they are only called from
* other functions in this module/logical unit. They are kept here for
* reference so we don't end up reversing the same function over and over again.
