Panda3DS

Panda3DS

Panda3DS is an HLE, red-panda-themed Nintendo 3DS emulator written in C++ which started out as a fun project out of curiosity, but evolved into something that can sort of play games!

Experimenting with new methods in emulation and unique features such as Lua scripting, we're here to make a difference!

Compatibility

Panda3DS is still in the early stages of development. Many games boot, many don't. Lots of games have at least some hilariously broken graphics, audio is WIP, and some QoL features are missing. However, even more things are implemented, such as most of the 3DS core required to play games, and various neat features, such as Lua scripting, discord bot support, support for some system apps, cheats, controller support, WIP amiibo support and many more! The emulator is constantly evolving, so make sure to take a peek every now and then!

For documenting game compatibility, make sure to visit the games list repository. For miscellaneous issues or more technical issues, feel free to use this repo's issues tab.

Why?

The 3DS emulation scene is already pretty mature, with offerings such as Citra which can offer a great playing experience for most games in the library, Corgi3DS, an innovative LLE emulator, or Mikage. However, there's always room for more emulators! While Panda3DS was initially a mere curiosity, there's many different concepts I would like to explore with it in the future, such as:

• Virtualization. What motivated the creation of this emulator was actually a discussion on whether it is possible to get fast 3DS emulation on low-end hardware such as the Raspberry Pi 4, using the KVM API. At the moment, Panda3DS is powered by Dynarmic rather than using virtualization, but this is definitely a concept I want to explore in the future.

• Debugging, reverse engineering and modding tools. While contributing to PCSX-Redux and collaborating with the other developers, I had the chance to find out how useful tools like these can be. They can serve as indispensable tools for the homebrew devs, modders, reverse engineers, as well as emulator developers themselves. Some tools can even become fun toys the casual user can mess around with. As such, I think they can really improve the experience in a project like this. Of course, I'd like to thank @nicolasnoble and the entire Redux team for helping me learn the value of these tools, as well as making me improve as a programmer.

• Trying out various other unique features, such as different graphics or audio enhancements, or supporting other niche things such as amiibo.

• Fun. Writing code is fun and I strongly encourage anyone to do it.

Keep in mind, these are all long-term plans. Until then, the main focus is just improving compatibility

How to build

Panda3DS compiles on Windows, Linux and MacOS, with only 1 (optional) system dependency, the Vulkan SDK. If you don't want to install the Vulkan SDK you can always build the emulator with only OpenGL support, by adding -DENABLE_VULKAN=OFF to the cmake command

All you need is CMake and a generator of your choice (Make, Visual Studio, Ninja, etc). Simply clone the repo recursively and build it like your average CMake project.

git clone https://github.com/wheremyfoodat/Panda3DS --recursive

cd Panda3DS && mkdir build && cd build
cmake .. -DCMAKE_BUILD_TYPE=Release -DENABLE_USER_BUILD=ON  # Set up compilers etc here if you'd like

<Invoke Make, Visual Studio, or whatever you would like to use>

*If you want to contribute to the project, you may not want to enable the ENABLE_USER_BUILD option and instead familiarize yourself with the various CMake options provided in the root CMakeLists.txt

How to use

Simply drag and drop a ROM to the executable if supported, or invoke the executable from the command line with the path to the ROM as the first argument like: Alber.exe MyGame.3ds Panda3DS can load ROMs in the following formats:

• .3ds/.cci
• .cxi/.app/.ncch
• .elf/.axf
• .3dsx

Both decrypted and encrypted dumps are supported. However for encrypted dumps you must provide your AES keys file by adding a sysdata folder to the emulator's app data directory with a file called aes_keys.txt including your keys. Currently .cia files are not supported yet (support is planned for the future), however if you want you can usually use Citra to extract the .app/.cxi file out of your .cia and run that.

Controls

Keyboard & Mouse

• Up analog W
• Down analog S
• Left analog A
• Right analog D
• D-pad Arrows
• A button L
• B button K
• X button O
• Y button I
• L button Q
• R button P
• Start button Enter
• Select button Backspace
• Touch Screen Left click
• Gyroscope Hold right click and swipe your mouse left and right (support is kind of shaky atm, but games that require gyro here and there like Kirby should work)
