Citra MMJ: A Nintendo 3DS Emulator for Android
Citra MMJ is a modified version of Citra, an open-source emulator for the Nintendo 3DS written in C++. Citra MMJ offers some features and enhancements that are not available in the official Citra app, such as resolution scaling, texture filtering, and external gamepad support. Citra MMJ can run many of your favorite 3DS games on your Android phone or tablet.
How to use Citra MMJ
To use Citra MMJ, you need to have a device that meets the following requirements:
- Android 8.0 or higher
- OpenGL ES 3.2 support
- At least 2 GB of RAM
- A decent CPU and GPU (Snapdragon 835 or higher recommended)
You also need to have a decrypted 3DS ROM of the game you want to play. You can dump your own games using a hacked 3DS console and a tool like GodMode9. Do not download ROMs from the internet, as that is illegal and may harm your device.
Once you have the ROM file, you need to place it in a folder on your device’s storage. You can use any file manager app to do this. Then, you need to download and install the Citra MMJ APK from a trusted source. Do not install APKs from unknown sources, as they may contain malware or viruses.
After installing the app, you need to grant it permission to access your storage. Then, you can launch the app and tap on the folder icon at the top right corner. You can then browse to the folder where you placed your ROM file and select it. The game should start loading and you can enjoy playing it on your device.
Features and settings of Citra MMJ
Citra MMJ has some features and settings that are different from the official Citra app. Here are some of them:
- You can enable or disable resolution scaling, which increases the internal resolution of the game up to 4x. This can improve the graphics quality, but also requires more processing power and may cause slowdowns or crashes.
- You can enable or disable texture filtering, which smooths out the pixelated textures of the game. This can also improve the graphics quality, but may cause some graphical glitches or artifacts.
- You can enable or disable linear filtering, which applies a smoothing filter to the screen output. This can reduce aliasing and jagged edges, but may also blur some details.
- You can enable or disable accurate multiplication, which fixes some lighting and shadow issues in some games. This may also improve performance in some cases.
- You can enable or disable accurate geometry shader, which fixes some graphical effects and animations in some games. This may also reduce performance in some cases.
- You can enable or disable shader JIT, which speeds up the emulation by compiling shaders on the fly. This may improve performance, but may also cause some instability or crashes.
- You can enable or disable hardware shader, which uses the GPU to render shaders instead of the CPU. This may improve performance and compatibility, but may also cause some graphical errors or crashes.
- You can enable or disable VSync, which synchronizes the frame rate with your device’s screen refresh rate. This may reduce screen tearing and stuttering, but may also increase input lag.
- You can adjust the audio volume and latency, which affects how loud and how delayed the sound is. Lowering the latency may improve synchronization, but may also cause crackling or distortion.
- You can adjust the touch screen sensitivity and position, which affects how responsive and accurate the touch input is.
- You can map external gamepads to control the emulator. You can use Bluetooth or USB gamepads that are compatible with Android. You can customize each button and axis according to your preference.
You can access these settings by tapping on the menu icon at the top left corner and selecting Settings. You can also access some quick settings by tapping on the gear icon at the bottom right corner while playing a game.
