Miyoo Flip vs Anbernic RG34XX SP: Which Budget Clamshell Wins

If you want a cheap handheld that folds shut, these are the two to look at. Both cost under $100. Both protect their screens when closed. Both run Linux and both take custom firmware.

They are not interchangeable. The Anbernic RG34XX SP is built around one very specific idea, which is playing Game Boy Advance perfectly. The Miyoo Flip is the more general purpose device with a screen shape that suits console libraries better.

Pick based on what you play most.

Specs at a Glance

The Screen Is the Real Decision

This is where the two devices genuinely diverge, and it is the only comparison point that should drive your choice.

The RG34XX SP has a 3.4 inch 720x480 panel in a 3:2 ratio. Game Boy Advance output is 240x160, which is exactly 3:2. That makes this panel a perfect 3x integer scale of a GBA frame. Games fill the screen edge to edge with no black bars and no scaling blur whatsoever. Nothing else at this price gets GBA this right.

The Miyoo Flip has a 3.5 inch 640x480 panel in 4:3. That is the classic console shape. NES, SNES, Genesis, Game Boy, Game Boy Color, PS1, and most arcade boards were made for 4:3 and fill this screen properly. GBA still works fine, it just sits inside the frame with small bars on the sides.

So the rule is simple. GBA heavy library, buy the RG34XX SP. Console heavy library, buy the Miyoo Flip.

Performance

The Miyoo Flip's RK3566 is the stronger chip. The RG34XX SP's H700 has more RAM behind it. In practice they land in a similar place, with a small edge to the Flip on the demanding end.

Neither is a PSP or GameCube machine. Both are excellent at everything through PS1. If you were hoping one of these would stretch further than the other in a meaningful way, they do not.

Analog Sticks

The RG34XX SP has two analog sticks. The Miyoo Flip has none.

That sounds decisive and mostly is not. The RG34XX SP's sticks are very small and sit low on the body, and reviewers consistently find them awkward. Time Extension called them "simply located too far down the unit to be of any genuine use," and noted that games needing both sticks make holding the device a balancing act.

So the RG34XX SP technically wins here, but do not buy it expecting comfortable 3D play. Both devices are really d-pad machines. If analog control matters to you, neither of these is the right purchase and you should look at the Anbernic RG35XX H or the RG35XX Pro instead.

Build and Hinges

Both fold, which is the whole point. A closed clamshell protects its own screen, which is the single best argument for this form factor on a budget device.

The Miyoo Flip has a hinge caveat you need to know about. The original V1 drew durability complaints, and Miyoo revised it. The V2, released around March 2025, uses a metal hinge. Buy the V2. Check listings for the metal hinge before ordering, and treat suspiciously cheap units as possible old stock.

The RG34XX SP has not had the same hinge concerns raised against it.

Firmware

Both take custom firmware and both have dual microSD slots, which means you can keep stock firmware on one card and something better on another. Swapping cards swaps the OS with nothing permanent.

The RG34XX SP has the wider firmware scene. Both muOS and KNULLI support it, since it inherits the enormous H700 community.

The Miyoo Flip is well served by KNULLI. That is fewer options, but KNULLI is genuinely good, so it is not much of a loss.

Which Should You Buy

Buy the Miyoo Flip if your library is console heavy through PS1, you want the 4:3 shape that suits NES, SNES, Genesis, and PS1, or you prefer the slightly stronger chip. Make sure you get the V2 with the metal hinge.

Buy the Anbernic RG34XX SP if GBA is the heart of your collection and you want the only panel at this price that scales it perfectly, you want the wider muOS and KNULLI firmware scene, or you want analog sticks present even if they are not great.

For most people the Miyoo Flip is the more versatile device and the 4:3 screen covers more systems well. For anyone whose collection is mostly Pokémon, Metroid Fusion, Golden Sun, Fire Emblem, and Advance Wars, the RG34XX SP is purpose built and hard to beat.

Frequently Asked Questions

Which has the better screen, the Miyoo Flip or the RG34XX SP?

Neither, they are shaped for different things. The RG34XX SP's 3.4 inch 720x480 3:2 panel scales Game Boy Advance perfectly. The Miyoo Flip's 3.5 inch 640x480 4:3 panel suits console systems like NES, SNES, Genesis, and PS1.

Does the Miyoo Flip have analog sticks?

No. The RG34XX SP has two, but they are very small and awkwardly placed, so neither device is good for 3D games.

Which is more powerful?

The Miyoo Flip's Rockchip RK3566 is the stronger chip, though the RG34XX SP has 2 GB of RAM against the Flip's 1 GB. In practice both handle everything through PS1 well and neither manages PSP.

What is the Miyoo Flip V2?

A revision from around March 2025 that replaced the original hinge with a metal one. The V1 hinge drew durability complaints, so the V2 is the version worth buying.

Can both run custom firmware?

Yes. The RG34XX SP supports muOS and KNULLI. The Miyoo Flip is supported by KNULLI. Both have dual microSD slots, so you can keep stock firmware on one card and custom firmware on another.
