Advantages
Superior Performance: Citra offers a significantly smoother and more visually impressive experience than the original hardware on capable devices.
Active Development: As an open-source project, Citra benefits from continuous improvements and updates from a dedicated community of developers.
Accessibility: It preserves and provides access to the entire 3DS library, which is crucial as the original console reaches its end-of-life.
No Console Modding Required: Unlike hardware mods, using Citra requires no physical alteration of your Nintendo 3DS console.

Disadvantages
High System Requirements: To run smoothly, especially with HD upscaling, Citra demands a relatively powerful PC or Android smartphone with a strong CPU.
Minor Compatibility Issues: While vast, game compatibility is not 100% perfect; some titles may have graphical glitches or audio bugs.
Legal Gray Area: Users must dump game ROMs from their own legally acquired game cartridges. Downloading commercial ROMs is illegal.
Lacks 3D Effect: The stereoscopic 3D effect of the original Nintendo 3DS hardware cannot be replicated on standard screens.

Tips for Using Citra
For the best experience on Android, seek out community-built forks like Citra MMJ, which often include crucial performance optimizations for Qualcomm Snapdragon chipsets.
Always prioritize using game files you have personally dumped from your own cartridges to ensure legality and optimal compatibility with Citra.
Tweak the graphics settings. Start with a lower resolution and gradually increase it to find the best balance between visual fidelity and performance on your hardware.
Use a Bluetooth gamepad for a more authentic and comfortable gaming experience on Android, as touch controls can be cumbersome for action titles.
