Device Overview: TrimUI Smart Pro

Let me clear up a piece of misinformation that follows this thing around before we go a single sentence further: the TrimUI Smart Pro does not have a 1080p screen, and it does not run an Allwinner H700. Both claims circulate, both are wrong. The panel is a 4.96-inch 1280×720 IPS, and the chip is an Allwinner A133P — a quad-core Cortex-A53 paired with an Imagination PowerVR GE8300 GPU, 1GB of LPDDR4x, and 8GB of eMMC. That matters, because the H700 you find in Anbernic’s RG35XX line is a genuinely different silicon path (Mali GPU, full 32-bit Linux driver support). The A133P is a touch faster on paper but it’s a 64-bit-leaning part with patchier 32-bit driver coverage, so some PortMaster ports and odd cores that run on an Anbernic simply won’t on this. Buy it for what it actually is.

What it actually is: a wide, horizontal handheld with a near-5-inch screen and dual sticks, sold for around $50-70 depending on bundle and seller. The pitch is screen real estate. Next to a 3.5-inch Anbernic RG40XX-H or anything in the Miyoo Mini orbit, the Smart Pro is a small slab you cradle in two hands, and the 16:9 panel makes PSP, widescreen homebrew, and TATE-mode vertical shooters look properly expansive. That’s the trade you’re signing up for — a bigger, brighter window in exchange for a chip that runs out of headroom well before the high-end systems do.

Emulation performance, generation by generation

Be realistic about the A133P. Everything 8- and 16-bit — NES, SNES, Genesis, TurboGrafx, Game Boy through GBA — runs at full speed with frames to spare; GBA in particular is flawless and looks great blown up on this panel. PS1 is the comfortable ceiling for “everything just works”: full speed, save states, no fuss. Above that, it’s selective. N64 via mupen64plus and Dreamcast via Flycast are playable on a curated library — the lighter and mid-tier games hold up, the demanding ones (think the heavier 3D N64 titles) stutter and need tweaking. PSP through PPSSPP is genuinely hit-and-miss: 2D and lighter 3D run, but the GE8300 gets pushed to its limit and the marquee titles want resolution and frameskip compromises. DS via DraStic runs well, though no touchscreen makes stylus-heavy games awkward. Saturn is effectively a no-go — that core is hungry and this chip doesn’t have it. And to be blunt about the upper bound: this is not a PS2 or GameCube machine. Don’t let anyone tell you otherwise.

Screen, build and controls

The 4.96-inch IPS is the headline and it earns it — bright, punchy color, strong contrast, good viewing angles. At 1280×720 over 16:9 it’s sharp enough at this size (~296 PPI) and the widescreen aspect is the right call for a horizontal device. The shell is matte plastic that feels solid rather than cheap, at 231g and roughly 188x80x17mm. Now the caveats, because there are real ones. The d-pad is the weak link — small, shallow travel, and genuinely frustrating for fighting-game quarter-circles and tight platformers. The dual analog sticks are low-set PS Vita-style nubs with RGB light rings; responsive enough, but some units ship needing calibration, and they’re small. The L2/R2 triggers can feel stiff. It does have full L1/L2/R1/R2, but no L3/R3 click. The device also warms up faster than you’d expect for the loads it’s handling.

Software and setup

Stock TrimUI OS is a competent Linux build with a decent launcher and a stack of emulators out of the box — fine for getting started, dull for living with. The reason enthusiasts buy this device is the custom firmware scene. CrossMix-OS is the popular pick: it keeps the stock UI but layers in a hundred-plus pre-tuned cores, PortMaster, Moonlight game streaming, themes, and auto-save states, and installs in roughly ten minutes off an SD card. Knulli, a Batocera/EmulationStation fork, is the alternative if you want the EmulationStation frontend, scraped box art, and OTA updates. MinUI exists too but caps you at PS1-and-below, so it deliberately ignores the N64/PSP/Dreamcast headroom you paid for. Practically: run stock to confirm the unit works, then flash CrossMix and don’t look back.

Price, value and who it’s for

At roughly $50 on the street (closer to $70-83 with SD bundles direct from TrimUI), the value math is straightforward — you’re getting a near-5-inch IPS screen and dual sticks for the price of a much smaller device. Buy it if you want a big-screen, two-handed handheld for everything up through PS1 flawlessly plus a curated diet of N64, Dreamcast, PSP and DS, and you’re willing to flash CrossMix. Skip it if you’re a fighting-game or precision-platformer player who lives on the d-pad, if you need guaranteed PSP fullspeed, or if PortMaster ports are central to your library — the A133P’s 32-bit driver gaps and that d-pad will both bite you. For a relaxed RPG-and-retro big-screen player, it’s one of the easiest budget recommendations going.
