Device Overview: One Netbook OneXFly

The One Netbook OneXFly is a Windows 11 handheld gaming PC, not a fixed-library console and not a cheap ARM emulation box. It launched in August 2023 on Indiegogo as one of the first pocket devices built around AMD’s Ryzen 7 7840U, the “Phoenix” APU that also powers the Asus ROG Ally and the Ayaneo 2S. What separates the One Netbook OneXFly from that crowd is packaging: at roughly 580 to 599g and 23mm thick, it undercuts the Ally on weight while wrapping the same silicon in a rounded shell that reviewers found genuinely more comfortable to hold. Because it is an x86 machine, it runs the actual Steam, Epic, Game Pass, and emulator ecosystems rather than a curated ROM menu. One Netbook, better known for its UMPC-style mini laptops, also lets buyers laser-engrave up to eight characters on the wings, a small touch that signals this is a boutique release rather than a mass-market one.

Emulation performance, generation by generation

Since the 7840U is a full Zen 4 CPU paired with a Radeon 780M (RDNA 3, 12 compute units), the OneXFly’s emulation ceiling sits far above any Rockchip or Allwinner handheld. Everything through the sixth generation is trivial: DuckStation (PS1), Dolphin (GameCube and Wii), PCSX2 (PS2), and Flycast run at full speed with upscaling and internal-resolution multipliers to spare. The seventh generation is where the chip earns its keep. PPSSPP (PSP) is flawless, Vita3K and Cemu (Wii U) are very playable, and RPCS3 (PS3) runs a large slice of the library at 30 to 60fps, though heavy exclusives still stutter and lean hard on CPU and RAM. Nintendo Switch emulation through the Yuzu and Ryujinx successors was the headline use case at launch, with demanding titles reaching 30fps or better at handheld wattage, but treat that scene as legally and technically volatile after the 2024 shutdowns. Fundamentally this device plays modern PC games natively, so emulation is a bonus rather than its reason to exist.

Screen, build and controls

The 7-inch IPS panel runs 1920×1080 at 120Hz with 10-point touch, and it is the OneXFly’s strongest single feature: ultra-thin bezels make the screen look larger than the chassis suggests, and 120Hz genuinely helps in lighter or frame-capped titles. It is an LCD, not OLED (that arrived later on the F1 Pro), and brightness is adequate rather than outdoor-proof. Controls are the other highlight. The analog sticks are Hall effect, so drift should never be a concern, and they sit in RGB-lit rings; the ABXY buttons, d-pad, and shoulders all drew praise, and the triggers have real pushback instead of mushy travel. The power button doubles as a fingerprint reader. Connectivity is generous for the size: two USB4 Type-C ports (charge while running a dock or eGPU), a USB-A 3.0 port, microSD, a 3.5mm jack, Wi-Fi 6E, and Bluetooth 5.2. The one hard compromise is the 48Wh battery, small for this power draw, which heavy games can flatten in well under 90 minutes.

Software and setup

Out of the box the OneXFly ships with Windows 11 and One Netbook’s OneXConsole overlay, which handles TDP (adjustable from about 4W to 30W), fan curves, and RGB. Windows on a 7-inch screen is the usual friction point: tiny touch targets, driver updates, and a desktop that was never designed for a d-pad. Most owners paper over this with a front end such as Playnite, Steam Big Picture, or the community HandheldCompanion tools that add gyro and per-game profiles. Because this is x86, the ARM-oriented custom firmwares (muOS, Knulli, ArkOS, ROCKNIX, OnionOS) simply do not apply here. The relevant alternatives are the desktop-class ones: EmuDeck installs and configures the emulators above in a single pass, while Batocera and the SteamOS-like Bazzite can be flashed to the SSD or a card for a console-style Linux experience, and dual-booting is common. Plan on an evening of tuning per-game TDP and resolution to land thermals and battery where you want them.

Price, value and who it is for

Launch pricing ran from about $739 for 16GB/512GB up to roughly $969 for 32GB/2TB and past $1,299 for the maxed 64GB/4TB build, noticeably more than a comparable ROG Ally, which is the OneXFly’s central value problem. You are paying a premium for the lighter, better-feeling chassis, the 120Hz 1080p screen, and USB4, not for extra performance; the 780M ceiling is identical to every other 7840U handheld. Buy it if you want the most comfortable, most portable way to run native PC and PS3-era emulation in your hands and you weight ergonomics and screen over battery life and price. Skip it if you want long unplugged sessions, a plug-and-play console feel from the first boot, or the cheapest route to Steam Deck-class gaming, because a Steam Deck OLED does that for less money and far less fiddling. It has since been superseded by the OLED F1 Pro, so the original now turns up discounted, which is when it makes the most sense.
