FPGB Mini Review: A Game Boy Pocket Mod for NES Cartridges

What the FPGB Mini Is

The FPGB Mini is a portable emulation handheld designed around a very specific idea: playing original NES cartridges on the go. Rather than relying on ROM files, it accepts the real thing, so your existing collection of grey cartridges has somewhere new to live.

Its proportions are worth noting straight away. The device is slightly wider than a standard NES cartridge, which means a cartridge slotted into it doesn't disappear into the body — it sits there, visible and unmistakable. That extra width is a deliberate part of the package rather than an accident of design.

For anyone who has watched a shelf of NES carts gather dust, the appeal is obvious. The FPGB Mini turns that shelf into something portable, letting you carry a handful of favourites and play them the way they were originally distributed. It is, at heart, a handheld built for people who still own the cartridges and want a reason to use them.

Design and Form Factor

The FPGB Mini is tiny enough that the best way to picture it is against the very media it plays. Rather than a bulky handheld or a full-size console, the device is built around a footprint that sits shoulder to shoulder with a Nintendo cartridge.

That comparison is the whole point of its design. A standard NES cartridge defines the scale: the FPGB Mini is compact and cartridge-adjacent, so it reads less like a traditional game system and more like a small companion piece to the cartridges themselves. There is no oversized shell or wasted plastic here, just a tight, purposeful form that keeps the hardware close to the size of the games it is meant to run.

The result is a device that feels almost pocket-sized next to conventional retro hardware, yet still clearly built for cartridges. It is a compact, cartridge-adjacent machine first and foremost, and that restraint shapes everything about how it looks and sits on a desk.

Playing NES Cartridges

The FPGB Mini accepts original Nintendo cartridges, so you can play the games you already own rather than relying on a built-in library. This is a cartridge-based NES handheld, and physical media sits at the centre of how it works.

If you have a shelf of NES cartridges, the FPGB Mini is designed to read them directly. There is no need to repurchase titles or hunt down digital versions of games you already have on a shelf. You insert the cartridge and play, which keeps the experience close to the original hardware.

That approach has practical appeal. Original cartridges hold up over time, and collectors often prefer playing on the media they grew up with. The FPGB Mini leans into that preference instead of asking you to abandon it.

For anyone with an existing NES collection, this is the key feature. The FPGB Mini is built for cartridge-based NES play, and original cartridges are what it is made to run.

The Takeaway

The FPGB Mini's appeal comes down to a single, tightly held idea: a handheld that plays real NES cartridges while staying almost as small as the cartridges themselves. That closeness in scale is the whole point. Rather than shrinking the games into a downloaded library, it keeps the physical media at the centre of the experience and builds the device around it.

The result is a machine that feels less like a modern console and more like a companion to the cartridge slot. You still handle the same grey plastic, still push a game in, still see it sitting there as part of the hardware. The FPGB Mini simply wraps that ritual in a form factor that slips easily into a pocket or a bag.

For anyone drawn to the tactility of cartridge collecting, that combination is the draw. It is a handheld sized to its media, not the other way around.
