Here's a new compact keyboard with a fun yet seemingly impractical design. The KeyBoy Advance from PromoType and Unikey is a relatively tiny 50% form-factor board, designed to resemble Nintendo's classic Game Boy Advance handheld, which debuted in 2001. The Game Boy Advance was the highly anticipated 32-bit follow-up to the original Game Boy and Game Boy Color and went on to sell over 81 million units in its various forms over the years.

Unikey's KeyBoy Advance is based on the original Game Boy Advance landscape shape and is available in a wide range of colors, including 2001-era purple and orange variants. There's also e-coated aluminum and translucent options for those looking to match the specific GBA handheld they had (or wanted) back in the day. The 50% HHKB layout keeps things compact, with the main letters and 10-key number row accounted for.

Starting from $275 USD, the KeyBoy Advance is definitely pricey and something crafted for enthusiasts and collectors. It's also a bare-bones kit, so you'll need to supply keycaps, switches, and things like stabilizers. The good news is that there are options to add a hot-swappable PCB with various plates (ALU, PC, CF, PP). The real start of the show, though, is how it captures all of the little details of Nintendo's classic handheld.

This includes replicating the shoulder buttons (with microswitches), battery cover, power indicator, and integrated speaker. Promo images for the KeyBoy Advance showcase it being held like a Game Boy Advance, hence the "impractical design" comment in the introduction. PC keyboards aren't meant to be held like gaming handhelds from the early 2000s, but this is still an impressive design that reportedly took several iterations to make it look and feel like a match for the Game Boy Advance.
