Storage Space Needed for Citra MMJ and ROMs
Citra MMJ APK: Typically around 50-100 MB. Game ROMs vary in size, usually ranging from 400 MB to 2 GB per title, depending on the game. Extra Storage: It’s recommended to have at least 5 GB of free space to accommodate the emulator, games, save files, and future updates.
How to Check If Your Android Device Supports Citra MMJ
Ensuring your device is compatible with Citra MMJ requires checking a few key hardware and software specifications. Start by confirming that your Android version is 8.0 (Oreo) or higher, as this is generally required for modern builds of Citra MMJ. Older Android versions may not support key features or permissions needed for the emulator to function properly.
Verifying CPU Architecture Compatibility (e.g., ARMv8-A)
Use apps like CPU-Z Droid Info, or AIDA64 to check if your processor supports 64-bit ARMv8-A architecture. Look under the CPU or System tab for entries like arm64-v8a or AArch64. If your device lists only armeabi-v7a or 32-bit, it will not run Citra MMJ, as the emulator requires 64-bit processing support.
Checking GPU Support (OpenGL ES 3.2 or Vulkan)
Use tools such as GPU-Z DevCheck or the Vulkan Hardware Capability Viewer app available on the Play Store. Check whether your device supports OpenGL ES 3.2 or Vulkan 1.0+, as these are required for 3D rendering in Citra MMJ. Devices with weak GPUs or only OpenGL ES 2.0 support may experience graphical glitches or be unable to run the app at all.
Tips to Check RAM and Storage on Your Phone
Navigate to Settings About Phone Memory to view total and available RAM. At least 3 GB of RAM is recommended for smooth performance.
