This is a work-in-progress project which aims at reverse engineering and documenting the NTR 2.0 custom firmware (CFW) for the Nintendo N3DS. The CFW contains some interesting features and tricks to learn from, such as

• the injection of code into foreign processes by temporarily modifying Kernel objects
• displaying in-game menus by writing to LCD registers
• "stealing" service handles from known locations of other processes
• hooking code
• implementation of a debugger
• client / server code
• a plugin system
• calling privileged ARM11 code using svcBackdoor()
• running games from other regions by patching their SMDH
