Released in 2023 by Data Frog, the GB300 arrives with the goal of being an ultra-budget retro handheld console. It comes preloaded with more than 5,000 games, supports seven classic platforms, and combines compact portability with nostalgia. Whether you want to relive the golden age of the ’80s and ’90s or introduce those classics to new players, the GB300 aims to be the perfect fit. In this review, we’ll find out if the GB300 actually delivers on its promises and if it can provide a quality retro experience without breaking the bank.
GB300 Design: Vertical and Compact
The GB300 goes for a small, straightforward design with clear inspiration from the classic Game Boy, a hit choice when it comes to nostalgia. Measuring 81 x 128 x 26 mm, it’s lightweight and slips easily into your pocket or backpack, making it ideal for gaming on the go, whether you’re traveling, on a work break, or unwinding at the end of the day. The grip is comfortable for its price range, and its ergonomic shape makes it easy to handle even for people who aren’t used to handheld consoles.
The shell is made of simple plastic. It won’t impress anyone with premium finishes, but it’s sturdy enough to handle daily use without issues. Within its goal of being affordable and functional, the GB300 delivers exactly what it promises.
Available in black and red, it keeps a discreet retro look that fits the spirit of the console.
GB300 Controls: A Step Up from the Sup Mini
The GB300’s controls deliver exactly what you’d expect from an affordable retro handheld, with a noticeable improvement over the Sup Mini. The D-pad feels more comfortable and responds better, though it’s still not as precise as on higher-end models. The action buttons, made of simple materials, may feel a bit soft or “mushy,” but they work well enough for most classic games without spoiling the fun.
On top of the basics, the GB300 includes Start, Select, and L/R shoulder buttons, which are essential for systems like the Super Nintendo and Game Boy Advance. While the finish and precision aren’t top-tier, the overall control experience is good enough to enjoy the games the system was built to run.
GB300 Connectivity: USB-C and AV Output
Connectivity is simple but effective. The GB300 includes a USB-C port for charging and a microSD card slot, allowing players to expand the library or even add new systems (including a hidden “eighth” console we’ll mention later). This flexibility is a nice touch for such a basic handheld.
Another highlight is the AV output, which lets you connect the console to a TV. That means you can enjoy retro classics on a bigger screen with friends, recreating the couch-gaming experience of the past. Simple, functional, and to the point.
GB300 Screen: 3-Inch TFT
The GB300 sports a 3-inch TFT display with a 320x240 resolution. It’s not as sharp or vibrant as IPS or AMOLED panels, but it gets the job done. Retro graphics look clear and colorful enough, with a 4:3 aspect ratio that preserves the original look of classic titles without stretching or distortion.
The visual experience is basic but functional: menus are readable, games display properly, and there are no noticeable lags or glitches. For what this console is meant to be, the screen holds up fine.
GB300 Battery: 800mAh, Up to 5 Hours
The GB300 comes with an 800mAh battery, which lasts about 4–5 hours depending on the system and the game. Lighter titles like NES or Game Boy last longer, while more demanding ones drain the battery faster. Still, that’s decent endurance for casual sessions.
Charging is done via USB-C, making it easy to find a compatible cable. A full charge takes around 1.5 hours, which is reasonable for a battery of this size. Straightforward and practical.
GB300 Processor and Storage: B210 with 128MB RAM
Powered by the HCSEMI B210 chip and 128MB of RAM, the GB300 may sound underwhelming on paper, but it’s more than capable of running classic consoles. It handles 8-bit systems smoothly and runs most 16-bit titles without major issues, offering a fluid retro experience. For fans of Mario, Sonic, or Street Fighter II, performance is more than enough.
Storage is provided by an 8GB microSD card already loaded with over 5,000 games. Better yet, you can replace it with a larger, higher-quality card to build your own custom library.
Operating System + Supported Platforms: 7 (or 8?) Consoles
The OS is simple, functional, and easy to navigate. It supports save/load states, a must-have for modern retro gaming, and organizes titles into folders. Adding new games is as easy as dropping ROMs into the “ROMS” folder on the microSD.
There’s also a hidden trick: if you create another “ROMS” folder inside the existing one and add Master System games there, the GB300 will automatically recognize and run them with great compatibility. It’s an undocumented bonus that expands its library to an unofficial eighth system.
Runs perfectly:
- NES / Famicom
- Game Boy
- Game Boy Color
- Mega Drive / Genesis
- PC Engine
- Master System
Runs decently:
- Super Nintendo
- Game Boy Advance
GB300 Price: The King of Budget Handhelds
Price is the GB300’s strongest point. It’s easy to find between $7 and $15 USD on AliExpress, sometimes even cheaper during sales. At this range, it’s nearly impossible to find something as complete.
Is the GB300 Worth It in 2025? Final Thoughts and Alternatives
If you’re just getting into retro handhelds and want something simple, cheap, and easy to use, the GB300 is a fantastic entry point. With a 3-inch screen, support for up to 8 classic systems, and thousands of preloaded games, it offers a nostalgic experience for under $15.
However, if you’re willing to invest a bit more, the R36S is a great option. It adds dual analog sticks, a larger screen, sturdier build, and even smooth PlayStation 1 emulation. And if you prefer a clamshell design like the Game Boy Advance SP, the Powkiddy V90 is another solid alternative in the same price range as the R36S, offering strong performance for SNES and GBA. In the end, it all depends on how much you want to spend and what kind of retro experience you’re looking for.
