Corgi3DS

Corgi3DS is a dog-themed LLE 3DS emulator. It can successfully boot a B9S-hacked firmware which then loads an ARM9 payload from an SD image, such as GodMode9. It is even capable of loading the home menu and some commercial games (Ocarina of Time 3D, Pilotwings Resort, and potentially others).

Compilation

Compilation requires Qt 5 and GMP. GMP is the library currently used for handling RSA crypto operations. Corgi3DS is cross-platform, but it may be difficult to compile on Windows due to the GMP requirement.

MSYS2

Make sure you're using MSYS2 MinGW 64-bit for this.

pacman -S mingw-w64-x86_64-{qt5,gmp,cmake}
git clone --recursive https://github.com/PSI-Rockin/Corgi3DS.git
cd Corgi3DS
mkdir build && cd build
cmake .. -G "MSYS Makefiles" -DCMAKE_BUILD_TYPE=Release
make

macOS/Linux

QMake

git clone --recursive https://github.com/PSI-Rockin/Corgi3DS.git
cd Corgi3DS
qmake
make

CMake (3.1+)

git clone --recursive https://github.com/PSI-Rockin/Corgi3DS.git
cd Corgi3DS
mkdir build && cd build
cmake .. -DCMAKE_BUILD_TYPE=Release
make

Usage

Required files:

3DS boot ROMs (boot9/boot11)
Encrypted NAND image dumped from GodMode9. NAND dumps require essential.exefs.

Optional files:

SD image
Encrypted 3DS cart dump (.3ds)

These files can be given through either the GUI or the CLI. Type -h or --help for a list of available commands in the command line.

Due to the risk of corrupted data, make backups of all NAND and SD images used.
