Citra MMJ: What It Is and What to Use Instead

Citra MMJ was a popular unofficial version of Citra built for Android. It once ran many 3DS games well on phones, with handy per-game settings and cheats. It is now outdated, though, and no longer the best pick. For Android today, Azahar is the maintained choice. This guide explains what MMJ was, how to use it, and what to use instead.

What is Citra MMJ?

Citra MMJ was an unofficial version of Citra made for Android. The community built it to run 3DS games better on phones than the standard build could at the time. It added useful features, like per-game settings and a simple cheat menu. For a while, it was the go-to way to play 3DS games on Android. The MMJ name came from its developer.

Is Citra MMJ still worth using?

Not really, not anymore. Citra MMJ is old and no longer updated. It has not kept pace with newer emulators. It still runs some games, but it misses the fixes and speed a maintained build brings.

For Android today, Azahar is the better choice. It is the maintained continuation of Citra and runs well on phones. See our Citra vs Azahar page. Our best 3DS emulator guide ranks the options too.

Citra MMJ vs the standard Citra

The two served different needs. Standard Citra was the main build for PC, and later for Android. Citra MMJ was an Android-only fork, tuned for phone performance. In its day, MMJ often ran smoother on weaker phones.

Now both sit behind Azahar, which is maintained and faster. For a full setup on modern Android, see our Android guide.

How to download and install Citra MMJ

Citra MMJ installs as an .apk file, like any Android app from outside the store. You download the file, allow your phone to install from that source, then open it to install.

Be careful where you download it. Since it is old and unofficial, many fake or tampered copies exist. Only use a trusted source. For a safer, current option, use Azahar instead.

Citra MMJ settings for performance

MMJ was known for per-game settings. You could change options for one game without touching the rest. To boost speed, you kept the resolution low on a weaker phone, and turned on the performance options it offered.

If games still ran poorly, that usually meant the phone was near its limit. A maintained build like Azahar handles this better today.

How to use cheats in Citra MMJ

Citra MMJ made cheats simple. While a game runs, tap the on-screen home button, then choose Edit Cheat. Paste your code as plain text, save it, and enable it. Our Citra cheats guide explains the code format and how to find codes.

Why Azahar is the better choice now

Azahar has replaced MMJ for most Android users. It continues Citra’s code, still gets fixes, and runs well on phones. It even offers two Android builds, one simple and one faster for large libraries.

You get better speed and support than MMJ can give. Get it from our download page, and follow our Android setup guide.
