Device Overview: Z-Pocket Game ZPG A1 Unicorn

The Z-Pocket Game ZPG A1 Unicorn is boutique brand Z-Pocket Game’s first Android handheld, and its whole reason to exist is the square screen. Where most 2024 handhelds chase a 16:9 rectangle, the Unicorn puts a 4.0-inch, 720×720 IPS panel dead center and asks you to play the systems that actually fit it. Under that square sits a MediaTek Helio G99, the same 6nm phone chip Anbernic drops into the RG556 and RG406V, so nobody should expect it to out-muscle its rivals on raw power. It competes on shape, not silicon, going head to head with the Powkiddy RGB30 and the pricier Anbernic RG Cube. At roughly $130 it is a niche pick that knows exactly which niche it wants.

Emulation performance, generation by generation

The Helio G99 pairs two Cortex-A76 cores at 2.2 GHz with six Cortex-A55 efficiency cores and a modest Mali-G57 MC2 GPU. Treat it as a capable mid-range Android emulation box, not a pocket PC. Everything through the 16-bit era, meaning NES, SNES, Genesis, Game Boy, GBA and TurboGrafx, runs at full speed in RetroArch with headroom for shaders and run-ahead. PlayStation 1 in DuckStation, Nintendo 64 in Mupen, and PSP in PPSSPP are comfortable, often at 2x or 3x internal resolution. Dreamcast via Flycast and Saturn via Yaba Sanshiro are mostly fine, though a handful of Saturn games still stutter. The interesting tier is the sixth generation: GameCube and Wii in Dolphin and PS2 in AetherSX2 or NetherSX2 are playable rather than guaranteed. Lighter titles hold their frame rate, but demanding ones dip and need per-game tuning. Nintendo DS through MelonDS and the 3DS through Citra forks land in the same “usually yes, sometimes no” bracket. Switch emulation is not a realistic goal on this chip; skip it entirely.

Screen, build and controls

That 1:1 panel is both the pitch and the catch. Systems with squarish output, such as Game Boy, GBA, NES, SNES, vertical arcade boards and especially the stacked dual screens of the DS, fill it beautifully; the DS in particular finally gets both screens at a usable size without an awkward layout. The trade-off is unavoidable. Any 16:9 or 4:3 content, meaning PSP, Dreamcast and most of the PS1 library, plays letterboxed or pillarboxed with black bars eating the extra pixels. At 720×720 across four inches the image is sharp, around 254 ppi, and the 60 Hz IPS panel is bright enough indoors. The body is plastic, weighs roughly 250 g, and hides an internal fan to keep the G99 from throttling. Controls are the strong point: dual asymmetric Hall-effect analog sticks with L3/R3 clicks and no drift to nurse, a proper eight-way D-pad, two pairs of shoulder buttons, a six-axis gyro and rumble. Front-firing stereo speakers and a 3.5 mm jack round it out. There is no video output.

Software and setup

Out of the box it runs stock Android 13, which means you assemble your own stack: RetroArch or standalone emulators from the Play Store, a front end like Daijisho or ES-DE, and ROMs sideloaded to the internal 128 GB or a microSD card. WiFi and Bluetooth are on board for controllers, downloads and streaming apps. Android is flexible but fiddly, and the Unicorn’s square resolution makes generic setup guides less useful than usual, so expect to spend an evening on aspect-ratio and per-core settings. The custom-firmware scene here is thin compared with Linux handhelds: there is no muOS, Knulli, ArkOS or ROCKNIX build for it. What exists is GammaOS Next, a stripped-down Android fork that removes Google bloat, improves battery life and boots closer to a dedicated console. Flashing it wipes the device, so back up first. If you want the plug-and-play simplicity of a Linux CFW handheld, this is not that; it rewards tinkerers.

Price, value and who it is for

At about $130 in China, climbing toward $200-plus once AliExpress markups, shipping and import duties land, the Unicorn is priced against the RGB30 and undercuts the RG Cube. Coming from a boutique brand better known for its tiny GBA-style Z-Pocket Game mini, it carries less support and community weight than an Anbernic, stock can be hard to find in the West, and documentation is patchy. Buy it if the square screen genuinely matters to you: DS, Game Boy, GBA and arcade collectors get a layout nothing 16:9 can match, and the Hall sticks and gyro are welcome extras. Skip it if your library leans PSP, Dreamcast or modern widescreen ports, where the black bars and the mid-tier G99 both work against you. It is a shape-first handheld, and it lives or dies on whether that shape is the one you play.
