STM32MP2 GK – A new GK handheld shifts the brain of the device to an STM32MP2 and leans hard into 3D acceleration. The result is a handheld that can run emulators from 8-bit classics all the way up to N64 games via a fork of mupen64—while keeping instant-boot ambitions, tou
The moment you see an STM32 platform pushing 3D acceleration, it’s hard not to feel like you’re holding a future prototype. That’s the pitch behind the latest GK handheld game console, built around an STM32MP2 that can do more than just run old software—it also brings OpenGL support to the mix.
This isn’t the first time a GK handheld has appeared. Version 3 also used STM32 hardware. but it leaned on an STM32H7S7L8 with a single Cortex-M7 clocked at 600 MHz and a 2D NeoChrom GPU. The new build takes a noticeably bigger step: the STM32MP2 pairs dual Cortex-A35 cores running at 1.5 GHz and adds a bonus Cortex-M33.
The device runs a custom OS called gkos. The developer claims it’s mostly POSIX-compliant and built for nigh-instantaneous boot times, which is exactly the kind of detail that matters when you’re trying to treat a handheld like a real console rather than a tinkering project.
Emulation is still the core appeal. The GK handheld can run emulators spanning from the 8-bit to the 32-bit era. With the added power and OpenGL support, it’s also positioned for N64 games via a fork of mupen64. There’s more for people who like computer classics too. including emulators for Atari ST and XL. along with a “PC” setup.
The PC angle is where the hardware’s capabilities start to sound almost conversational: DOSBox is said to deliver performance equivalent to a 50 MHz 486. That’s enough to run DOS classics like DOOM, and the creator notes better performance is likely if you use the native-running port of SDL-DOOM.
Control and display upgrades round out the picture. The handheld adds extra inputs compared to the previous version and features a bigger screen. It also brings Wi‑Fi to the device. For movement-based play, there are accelerometers for tilt control, and the touch input on the screen is supported as well.
If the form factor didn’t give it away. the GK handheld would be easy to describe as a capable little computer—because the software library and the mix of 3D graphics. emulation. and connectivity point in that direction. The hardware may look like a handheld console. but under the hood it’s chasing something closer to full computing freedom. just in a pocket-sized package.
