The Nintendo 3DS has one of the best libraries of any handheld, and 3DS emulation has come a long way. After the original Citra project shut down, the community carried the work forward. Azahar is the modern, actively developed 3DS emulator that most people now use.

This guide covers Azahar on handhelds. We look at the best devices, including the standout option for true dual screen play, plus the install steps, the system files you need, and the settings that matter. We only ever cover playing games you legally own.

What 3DS Emulation Needs

The 3DS has the same two screen design challenge as the DS, plus more graphical horsepower to emulate. A few things matter:

• Two screens worth of display. The 3DS used a top screen and a bottom touchscreen. You need a layout that shows both, or a device with two physical screens.
• A capable GPU. 3DS games upscale beautifully, and the higher you push internal resolution, the more GPU you want.
• Touch input. The bottom screen is a touchscreen. A device with its own touchscreen makes this effortless.

The good news is that 3DS emulation upscaled on a modern handheld can look better than the original hardware ever did.

Best Handhelds for 3DS Emulation

This is the one category where a special device exists.

• AYN Thor. The Thor has two physical AMOLED screens, which makes it the definitive 3DS device. The top game screen and the bottom touchscreen work exactly as the original hardware intended.
• AYN Odin 3 and Odin 2 Portal Pro. Powerful single screen devices that upscale 3DS beautifully, with the two screens stacked or arranged on one panel.
• Retroid Pocket 6. A strong, affordable single screen option with a touchscreen for the bottom panel.
• Steam Deck and PC. Excellent for 3DS, with lots of GPU headroom for high resolution upscaling.

Installing Azahar

On Android Handhelds

1. Download the latest Azahar build from the official project page or its official GitHub releases.
2. Install the APK, allowing installs from unknown sources if needed.
3. Launch Azahar once so it sets up its folders.
4. Add the system files and your games (next sections).

On Steam Deck and PC

Azahar runs on Windows, Linux, and macOS. On the Steam Deck, the easiest path is through a front end. Both our RetroDECK setup guide and EmuDeck setup guide cover managing it. RetroDECK added Azahar in a recent update.

System Files and Your Games

This is the part to do correctly, and it is similar to other Nintendo systems.

3DS emulation needs encryption keys and system files that come from a 3DS console. The only legal source is a 3DS that you own. You dump the keys and your games from your own console using homebrew tools such as GodMode9. We do not link to or describe ROM download sites, and we do not cover obtaining games or keys you do not own.

Once you have dumped your own games, they will be in a 3DS game format that Azahar can open. Point Azahar at the folder, and your titles appear in the library.

A simple rule. If it did not come off a console you own, this guide does not cover it.

Settings That Matter

A few settings make a big difference on handhelds.

• Internal resolution. Push this up for sharp, clean visuals. Higher settings look great but cost GPU power. Start at 2x and climb if your device keeps full speed.
• Screen layout. On single screen devices, choose a stacked or side by side layout. On the AYN Thor, assign the top screen to the top panel and the bottom screen to the touchscreen.
• Touchscreen input. If your device has a touchscreen, enable direct touch for the bottom screen. If it does not, map the touch cursor to the right analog stick.
• Shader and accuracy options. Leave these at sensible defaults unless a specific game needs a change.

Saves and Backups

Azahar stores saves in its data folders. Back them up before app updates or device moves. Our save state management guide and how to back up saves across firmware updates cover safe habits.

Frequently Asked Questions

What is Azahar?

Azahar is the modern, actively developed 3DS emulator that the community built after the original Citra project ended. It runs on Android, Windows, Linux, and macOS.

The AYN Thor, because it has two physical screens. Powerful single screen devices like the AYN Odin 3 and Retroid Pocket 6 are also excellent.

Yes. You need encryption keys and system files dumped from a 3DS you own, along with your own dumped games. We only cover playing games you own.

Yes. Raising the internal resolution makes 3DS games look sharper than the original hardware. Higher settings need more GPU power.
