The Odin 2 Portal Pro is the handheld we recommend most often for Switch emulation, and it is also the one where the biggest setup mistake is the easiest to make: treating a 7 inch 1080p panel the way you would treat a 5 inch one.
This is the order to set it up in. You need a microSD card, a cable and the game backups you already own, and about ninety minutes.

What You Need
- An AYN Odin 2 Portal Pro. One configuration, which makes this simpler than most: a Snapdragon 8 Gen 2 with an Adreno 740, 12GB of RAM and 256GB of UFS 4.0 storage.
- A microSD card, 256GB as a floor. Buy a known card from a seller you trust.
- A USB-C cable and a computer, or a Wi-Fi transfer app.
- Your own game backups and BIOS files, from hardware and discs you own.
Step 1: First Boot, and the Settings to Change
Android 14 with the Play Store unlocked, so the opening is painless. Run the normal setup, connect to Wi-Fi, let any pending update finish, then change these.
- Screen timeout to 10 minutes.
- Developer options on, by tapping the build number seven times. Needed for sideloading and for turning down the animation scale.
- Set the panel to 60Hz for emulation. This matters more here than on a smaller device. A 7 inch 1080p OLED at 120Hz is a meaningful power draw, and nothing you emulate benefits. Leave 120Hz for streaming, where it is genuinely good.
- Turn off adaptive brightness. Large OLED, dark game, hunting backlight, distracting.
- Set the fan curve. It is adjustable. A quiet profile up to PS2 and an aggressive one for Switch is what most owners settle on.
Step 2: Decide on a Launcher
The stock Odin Launcher is good and you can keep it. That is genuinely the recommendation for most people on this device, and it saves an hour.
If you want a library frontend, Daijisho, ES-DE for Android and Beacon are the three Odin owners use. See our Daijisho setup guide and ES-DE setup guide.
One 7 inch note on frontends. On a panel this size, the frontends that scale their own interface cleanly are worth a look before the ones that do not, because a frontend designed for a 5 inch screen can look oddly sparse here. That is a matter of taste rather than function and it is the kind of thing worth trying two of.
The shortcut. EmuDeck for Android installs a sensible emulator set and builds the folder structure in one pass. On a Play Store unlocked device it is the fastest route through the next two steps.
Whatever you choose: emulators first, files second, frontend scan last.
Step 3: Install Emulators, by System
RetroArch from the Play Store for everything up to PS1, with only the cores you need.
Mupen64Plus Next inside RetroArch for N64.
Flycast for Dreamcast, with its BIOS covered in our Flycast setup guide.
PPSSPP for PSP. On a 7 inch 1080p panel, PSP is one of the systems that benefits most from this device, because 3x the PSP's native resolution is 1440x816 and the panel has the pixels to show it.
Vita3K for PS Vita, covered in our Vita3K setup guide. The Vita's own screen was 5 inches at 960x544, so a 7 inch 1080p display is a straightforward upgrade for that library.
Dolphin for GameCube and Wii. Both run well on this chip, GameCube comfortably at 2x to 3x native.
A PS2 emulator from the AetherSX2 family, covered in the AetherSX2 setup guide. Most titles at 2x to 3x native.
A Switch emulator. This is what the device is known for, and which one you pick is the real question. Our Eden vs Kenji NX vs Citron comparison is the current answer, and the Snapdragon 8 Gen 2 with an Adreno 740 is one of the best supported combinations in that whole corner, which is the practical reason this device gets recommended so consistently.

Switch 2 is experimental everywhere in 2026. The Portal Pro is a credible platform for the attempt and not a reason to buy it. Background in our Switch 2 emulation guide.
Step 4: Storage, Folders and BIOS
Format the card as portable storage, not adopted internal. Adopted storage encrypts it to this device and you lose the ability to read it in a computer.

/Saves
BIOS files in one folder, pointed at by each emulator. PS1, PS2, Dreamcast and Vita each need their own, from hardware you own. A misplaced BIOS is the usual reason an emulator refuses a game that is otherwise fine. The general version is in our ROM and BIOS organisation guide.
This device kept the fast storage. The Portal Pro ships UFS 4.0, where late batches of the newer Odin 3 went to UFS 3.1. That makes the internal 256GB genuinely worth using for the systems with large files: Switch, Wii and PS2 on internal, retro systems on the card. Shader cache and save state writes are where you feel it.
Step 5: GPU Drivers, and Why This Device Has It Easier
The same step as on any Android handheld running demanding emulation, with one advantage worth knowing.
What the step is. Android ships a vendor Vulkan driver. Emulators of demanding systems ask more of a Vulkan driver than any phone game does, so community builds of Mesa's Turnip, the open source Vulkan driver for Adreno GPUs, often run those emulators better. They load into an emulator through a driver loading layer, without rooting the device and without touching the system driver.
Why the Portal Pro has it easier. The Adreno 740 in the Snapdragon 8 Gen 2 has been a Turnip target for years, and it is in the same chip generation as a large number of phones, which means the driver work has had far more testing than a brand new part gets. The newer Odin 3's Adreno 830 only got a dedicated maintained build during 2026. Here you are picking from mature options rather than waiting for one.
How to do it. Download a driver package from the project's own releases page, open your emulator's graphics settings, find its GPU driver picker, import and select. Keep the stock driver selectable and compare per game, because a community driver is a set of tradeoffs rather than a strict upgrade.
Never take a driver package from a video description or a forum attachment. It is code you are asking an emulator to load.
Step 6: Making the 7 Inch Screen Work For You
The thing that makes this device pleasant is also the thing that makes a careless setup look worse than it would on a smaller handheld. A 7 inch panel shows you every scaling decision.
Use integer scaling on the retro systems. On a 1080p panel, 5x of a 240 pixel tall system is 1200, which overshoots, so 4x at 960 lines with a border is the clean choice. A border on an OLED is actually black, so it costs you nothing but area.
Turn the shaders up, not the resolution. For NES, SNES and Game Boy, a 7 inch screen is where a decent CRT or LCD shader stops being a novelty and starts looking correct. Raw upscaling at this size looks flat.
Leave the 3D systems at a sensible multiple. GameCube and PS2 at 2x native land close to 1080p and look right. Pushing 3x or 4x on a 1080p panel spends battery on pixels the screen cannot show.
The one system that wants everything you have is PSP, where 3x native is 1440x816 and genuinely visible on a panel this size.
Step 7: Streaming and PC Games
Streaming is excellent here and the 7 inch 1080p panel is the reason. Steam Link from a home PC, plus the cloud services, all look better on this device than on anything smaller. This is the case where keeping 120Hz on is worth the power.
Windows games locally means a translation layer, and our Winlator setup guide covers it. Older and lighter titles work, modern ones do not. The Steam on Android options page compares the routes.
Replacing Android with Linux is the third option and the Odin family handles it well. See ROCKNIX and native Steam.
Known Problems, and What to Do About Them
Battery draining faster than you expected. Check the refresh rate first. A 7 inch 1080p OLED at 120Hz costs real power and emulation gains nothing from it.
A Switch game runs badly. Try a different emulator before you try a different driver. On this chip the emulator choice is usually the bigger lever, which is the opposite of the situation on the newer Odin 3.
It is big. This is not a fixable problem and it is worth saying plainly: a 7 inch handheld is a bag device, not a pocket device. If that is wrong for you, the Retroid Pocket 6 comparison covers the same chip in a smaller body.
Fan noise. Adjustable curve. Quiet up to PS2, aggressive for Switch.
Saves vanishing or a card that stops mounting. Nearly always the card. Our microSD corruption guide has the diagnosis and the best microSD cards covers buying a genuine one.
Frequently Asked Questions
How long does setting up an AYN Odin 2 Portal Pro take?
About ninety minutes done properly, or under an hour if you let EmuDeck for Android install the emulators and build the folders. The screen and scaling settings in step 6 are the part people skip and then wonder why a smaller handheld looked sharper.
Should I keep the stock Odin Launcher?
Yes, for most people. It is one of the better stock launchers in the category and keeping it saves an hour. Daijisho, ES-DE and Beacon are the common replacements if you want a library frontend.
Do I need custom GPU drivers on the Odin 2 Portal Pro?
Less urgently than on the newer Odin 3. The Adreno 740 has been a Turnip target for years with far more testing behind it, so the stock driver is a reasonable starting point and a community driver is a tuning step rather than a rescue. For Switch titles specifically it is still worth trying.
What refresh rate should I use?
60Hz for emulation and 120Hz for streaming. On a 7 inch 1080p OLED the difference in battery is noticeable, and no emulated system benefits from the higher rate.
What microSD card should I use?
256GB as a floor, 512GB or larger for disc based libraries. Format it as portable storage rather than adopted internal, and buy from a seller you trust. The internal 256GB is UFS 4.0 and genuinely faster, so keep Switch, Wii and PS2 there.
Is the Odin 2 Portal Pro still worth buying over the Odin 3?
For Switch 1 specifically it remains the most consistent recommendation, because its chip and GPU have the longest emulator and driver track record, and it kept the faster UFS 4.0 storage the Odin 3 gave up in later batches. The Odin 3 is faster and better suited to Switch 2 attempts. Our full comparison is here.
Can it run Switch 2 games?
Experimentally, like every device in 2026. It is a credible platform for the attempt. Expect crashes and do not buy it for this.
Does the 7 inch screen make emulation look better or worse?
Both, depending on your settings, which is why step 6 exists. Integer scaling and a good shader make retro systems look better here than on any smaller handheld. Careless upscaling looks worse here than anywhere, because the panel shows you every decision.
