The OneXSugar Wallet has entered the spotlight and it’s not just riding the retro handheld wave, it’s folding it. One-Netbook’s latest experiment is a clamshell-style Android device with an 8.01-inch foldable OLED screen, built for emulation fans and pocket-size portability. With a seamless display and dual-screen nostalgia baked in, it’s aiming to do what Surface Duo couldn’t make a foldable feel complete.
OneXSugar Wallet combines portability with a full bendable display

Foldable phones have been trending for years, but One-Netbook is steering that tech straight into the handheld scene. The OneXSugar Wallet folds like a wallet, plays like a console, and slots easily into a pocket something the larger Sugar 1 never quite managed. Its 4:3 aspect ratio and high-res 2480 × 1861 OLED screen are tailored specifically for retro systems that demand vertical space think DS, 3DS, and more.
Unlike devices with two separate displays, the Wallet uses a single continuous screen. No bezel gap. No syncing issues. Just a unified playfield that delivers the closest thing yet to a dual-screen system done right.
Built-in controls and modern flair for classic titles
The Wallet comes fully equipped with:
- A traditional D-Pad
- Low-profile dual analog sticks
- Face buttons
- Shoulder triggers
All nestled around a clean, minimal clamshell form. It’s compact enough to fit in oversized wallets (yes, seriously), yet boasts enough screen real estate for full-scale gaming sessions.
The design cues clearly borrow from foldables like Samsung’s Z Flip 7 or the Pixel Fold Pro. But unlike those, this one’s not for calls, it’s for Castlevania. That alone gives it a different kind of appeal.
Foldable fun, but durability questions remain
As with all foldables, the Wallet faces familiar pitfalls: hinge reliability, crease visibility, and dust resistance. One-Netbook hasn’t revealed technical details yet, but retro fans are already watching closely. The company’s past risk-taking with devices like the Sugar 1 proves it’s not afraid to challenge convention even if that means living on the edge of engineering.
Still, the single-screen foldable concept on a retro handheld? That’s a first. Even Microsoft’s Surface Duo struggled with split screens and app compatibility. The Wallet appears more focused, more specific and possibly more successful because of it.
Retro emulation has a new poster child on the way
The OneXSugar Wallet is shaping up to be a potential go-to for DS and 3DS emulation, largely thanks to its unusual screen. Fans looking for a compact handheld that avoids the bulky Game Boy-style clone design might finally have an option that doesn’t feel like a compromise.
It’s officially labeled “Coming Soon 2026,” which could place a release window somewhere in the summer or fall. If early reactions are any hint, One-Netbook may have a surprise hit on its hands provided the hardware holds up to long-term use.
