The retro handheld market has rarely been this crowded or creative. Manufacturers are shipping devices with sliding screens, dual-display clamshells, and rotating form factors, all competing for a growing nostalgia-driven audience. Yet for all that variety in hardware, the controls themselves rarely change. You get what you get, and if the layout doesn’t suit how you like to play, that’s not the manufacturer’s concern.
That’s the gap one Reddit user set out to address with the RG Modular, a fan-made concept that came shortly after the release of Anbernic’s RG Rotate. Rather than locking players into a single control layout, the concept centers on a core screen unit with swappable modules that slot into side and bottom rails. The game dictates the controller, not the other way around.

At the center of the RG Modular is a 4-inch IPS display running at 1080×1080 pixels, a square format that works cleanly for both retro and modern titles. Android powers the device, offering full app access, proper sleep mode behavior, Wi-Fi 6, Bluetooth 5.4 for wireless streaming, and a 3.5 mm headphone jack for when you’d rather keep the audio to yourself.
Blast through a library of classic arcade titles or beat-’em-ups, and the D-pad module is all you’d need. It’s compact, locks cleanly into the bottom rail, and keeps the whole assembly slim enough to hold comfortably in portrait mode. The result feels close to something from the original Game Boy era, scaled up just enough to feel substantial but still pocket-friendly enough to bring along.
Pop on the horizontal configuration for something more demanding, and the RG Modular begins to feel like a contemporary gaming device. A left module with a D-pad and analog stick snaps to one side, a right module with face buttons and a second stick clicks onto the other, and suddenly the same screen unit that ran retro arcade titles now handles 3D games and wirelessly streamed content.
Perhaps the most unexpected addition in the lineup is the QWERTY keyboard module. Swapped in for the standard controls, it nudges the device toward productivity, text entry, or emulating handheld systems that relied on keyboards. It signals that the concept isn’t purely about gaming, and that a modular form factor can cover considerably more ground than any one fixed layout could manage.
The post drew enthusiastic praise, but the community did raise practical questions. Some users noted that a D-pad-only module might leave the device feeling top-heavy, and the broader modular concept raises fair concerns about cost, connection point durability, and whether the rail system can stay snug through regular use.
It’s not the first attempt at a shape-changing handheld console, either, with the likes of the GAMEMET E5 and ONEXSUGAR testing the waters first. It’s worth noting that the RG Modular is only a concept, but concepts like this one carry weight in the retro handheld community. Manufacturers have also occasionally taken cues from what enthusiasts build, turning fan ideas into products people didn’t know they needed.
