If you are trying to play games using the Citron Switch Emulator on Android but can't launch any games because they all go to a back screen or crash. This article will guide you through some solutions. Citron, like all other Switch emulators, is extremely hardware-intensive, so if your device does not meet the minimum performance requirements, 99% of games simply won't work. You just need to accept this and move on.

Takeaways:

  1. Learn how to stop games from crashing to a black screen in Citron Emulator on Android.
  2. What is causing games to black screen in Citron Emulator on Android?

Black Screen Problem in Citron Switch Emulator on Android Causes

The black screen issue almost always occurs when launching a game that begins to load, briefly shows the controller layout, and then returns to the main menu or remains stuck on a blank screen. This problem is most common on devices with Mali GPUs, though it can also affect other chipsets as well. It's almost always caused by one of the following things:

  • Outdated emulator version
  • A crap phone (Low end device)
  • Corrupted or incomplete game files
  • Temporary bugs in Citron’s Android build

Note: If you have a cheap phone, you might as well give up now.

HARDWARE REQUIREMENTS (IMPORTANT)

While minimum requirements are listed below, I wouldn't bother trying on a device that just scrapes through. Even the recommended specs are going to be hit and miss for a lot of games.

CPU

  • Any ARM64-v8a or newer CPU.
  • 6 threads or more are recommended.
  • Minimum: Qualcomm Snapdragon 695 / MediaTek Dimensity 810 or equivalent (e.g., devices from late 2021 onwards in budget/mid-range)
  • Recommended: Qualcomm Snapdragon 8 Gen 1 / MediaTek Dimensity 8100 or equivalent (e.g., devices from 2022/early 2023 flagships or high mid-range)
  • Optimal: Qualcomm Snapdragon 8 Gen 3 / MediaTek Dimensity 9300 or equivalent (e.g., recent flagship devices)

RAM

  • Integrated GPUs use system RAM, so adequate RAM is crucial.
  • Highest possible frequency is strongly recommended.
  • Minimum: 8 GB
  • Recommended: 12 GB
  • Optimal: 16 GB or more

GPU

  • Modern Android devices use integrated GPUs (part of the SoC).
  • Vulkan 1.1 compatible hardware and drivers are mandatory. OpenGL ES 3.2 compatibility is also expected on modern hardware.
  • Half-float support and VP9 decoding support are recommended.
  • Minimum: Qualcomm Adreno 619 / ARM Mali G68 MC4 or equivalent (typically found in the minimum recommended CPUs)
  • Recommended: Qualcomm Adreno 730 / ARM Mali G610 MC6 or equivalent (typically found in the recommended CPUs)
  • Optimal: Qualcomm Adreno 750 / ARM Mali G720 MC12 or equivalent (typically found in the optimal CPUs)

IMPORTANT: Mobile CPUs will not reach the same performance as their desktop counterparts due to thermal, power, and technical limitations.

How to Fix Citron Emulator on Android Black Screen When Launching Games

Always make sure that you are using the latest version of Citron Android. The development team regularly releases updates that fix known issues, improve performance, and expand hardware compatibility. Check for updates within the emulator or download the newest release from the official Citron website or trusted community channels. Once you have updated the emulator, also update your prod.keys and firmware.

Check the Game Files Actually Work

A black screen can also indicate that the game files are corrupted or incomplete. If the same game works properly on the PC version of Citron, then the issue likely lies in the Android installation or file transfer process. Try re-downloading or re-transferring the affected title. Make sure your game dumps are clean and unmodified.
