GAMEMT MTX: An $80 Handheld With a Real GBA Cart Slot
The pitch is almost too simple: a $79.99 Linux handheld that reads your original Game Boy Advance cartridges. The GAMEMT MTX has been drifting through Discord servers and social feeds for months, and it’s finally orderable — $79.99 direct from GAMEMT, or about $71 on AliExpress with the code 9RHH.
Under the shell it’s an Allwinner T509 with a PowerVR GE8300 GPU, 1GB of RAM, 8GB of internal storage, and a 3.95-inch 720x720 square panel. No sticks. Digital shoulder buttons only. A 3000mAh battery charged over 5V/2A, plus Mini HDMI and USB-C OTG out. It is, in other words, a very specific machine built for a very specific kind of player — and the spec sheet gives away exactly who that is.
A Square 720x720 Panel Is the Smartest Spec on the Sheet
That 1:1 display looks like an odd choice until you do the math. The GBA outputs 240x160, so a 3x integer scale lands at exactly 720x480 — a pixel-perfect horizontal fit on a 720-wide panel, with letterboxing above and below. At 257 PPI it’s sharp, and crucially it’s an integer multiple, which is the difference between crisp sprites and shimmering garbage on a screen this small. The square shape also quietly serves vertical arcade shooters, Game Boy, and the handheld-to-TV aspect crowd that most budget machines ignore.
According to GAMEMT’s own listing the slot officially covers GBA carts, though it would be genuinely strange if Game Boy and Game Boy Color didn’t also work — the voltage and pin behavior are close enough that omission feels like a spec-sheet gap rather than a hardware limit. One caution: the listing also throws ‘FPGA’ into the software field next to Linux (ARM), which is almost certainly a copy-paste error. A T509 is a standard ARM SoC with an emulation front end, not an FPGA recreation, so don’t expect the cartridge-first polish of an Analogue Pocket from an $80 device.
T509 Debut and the PSP 2X Claim: Believe It When You See It
GAMEMT appears to be the first to ship Allwinner’s T509, paired here with a PowerVR GE8300 and just 1GB of RAM. Prior leaks pegged that combination at PSP emulation up to 2X resolution, which sounds impressive until you remember the MTX has no analog sticks and only digital shoulder buttons. The PSP and PS1 libraries lean hard on analog input, and 1GB of RAM is thin headroom for a PSP emulator that already fights for memory bandwidth. This is a machine built to shine on 8-, 16-, and 32-bit 2D libraries — the moment a game asks for a nub, it falls apart.
The battery reinforces that framing: 3000mAh is modest even by budget-handheld standards, so treat this as a commuter’s companion for short bursts, not a marathon-flight device. At $71–$80 the MTX isn’t competing with a Steam Deck or an Android handheld — it’s aimed at the same crowd as AYANEO’s $89 KONKR Pocket Advance: the person with a drawer full of dusty GBA carts and no way to play them. For that player, a pocketable cartridge-honoring machine at this price is a genuinely good excuse to buy in; everyone else should wait for real-world T509 performance numbers before committing.
