MICRO BOY ADVANCE™
MICRO BOY ADVANCE™
Eight consoles. One IPS screen. Smaller than a credit card.
2.75″ × 1.6″ × 0.5″

The first one proved a console could be this small and still work.
This one proves it can be this small and still be good.
IPS display. ALPS micro-switches. Thirty years of gaming history on a single card.
The screen is the upgrade
The original ran a basic panel. This one runs IPS — and if you've ever tilted a cheap handheld and watched the colors invert into a washed-out mess, you already know why that word matters.
IPS means the image holds from any angle. Blacks stay black. Colors stay saturated at the edges of the panel instead of ghosting out. You can hand it across a table for someone to see without turning it to face them.
At 240 × 160 with near-1:1 pixel mapping, sprites land where the artists drew them — no stretching, no interpolation, no smeared upscale. It's the difference between a screen that displays a game and a screen that does it justice.
Eight systems. One pocket.
This is the part that makes people put their phone down.
The Advance doesn't just handle one console's library. It runs eight, spanning the 8-bit era, the 16-bit generation, two handheld families, and the first wave of 32-bit disc games:
GB · GBC · GBA · NES · SFC/SNES · Game Gear · Master System · PC Engine
plus early PS1 titles
That's roughly three decades of gaming, in a device that hangs off a keyring. Load a single microSD card and carry the entire history of handheld and home console gaming in something smaller than the wallet it sits next to.

The details
⌁ ALPS micro-switches.
Not membrane pads. Not rubber domes. The d-pad and face buttons use genuine ALPS micro-motion switches — the same component class you'd find in a mechanical mouse. They register a real, definite actuation rather than a mushy press.
⌁ Built-in lithium cell, ~2.5 hours.
A square lithium battery sized to the chassis, charging over USB. Around two and a half hours of continuous play — a full commute each way, or an entire flight delay.
⌁ Open-source firmware.
The system runs a modified build of FunKey OS, an open, community-developed handheld platform. Not locked-down mystery firmware from a factory — an actual project with actual documentation behind it.
⌁ Smaller than a credit card.
2.75 inches tall, 1.6 wide, half an inch thick. Shorter and narrower than the card in your wallet. It genuinely disappears into a pocket.
⌁ Ten colorways.
Solid black, blue, purple and white — or the translucents: clear black, clear white, and two clear greens where the board and ribbon cable show straight through the shell.
Every Micro Boy Advance is modified and finished by hand. Not assembled by robot on a line — cut, fitted and polished by a person, one unit at a time.

Questions
Is it really smaller than a credit card?
Shorter and narrower, yes — thicker, obviously, because there's a battery and a screen in it.
What does IPS actually change?
Viewing angles and color. Cheap panels wash out the moment they're not dead-on. This one doesn't.
Will PS1 games run well?
The hardware supports the format, and lighter titles play. Treat 8- and 16-bit as the core experience and PS1 as a bonus rather than the reason you're buying.
Are the scratches really that noticeable?
Noticeable enough that we put it in the product description rather than the fine print. Look at our photos of actual units — not renders — and decide.
Can I load my own files?
Yes. Standard microSD.
