In the 1990s, Nintendo was raking in the cash with the Game Boy, and SEGA wanted a piece of the handheld market pie. Enter the Game Gear, a technologically superior handheld with a color screen, the ability to play Master System games, and a handful of awesome first-party titles. While the Game Gear never managed to budge the Game Boy from its throne, it still earned a cult following, and I consider myself one of those dedicated fans. In fact, the Game Gear was my first handheld ever, and since I first laid hands on it all those decades ago, it’s held a special place in my heart. So, to pay homage to my beloved Sega portable, I decided to create the ultimate system using all the best Game Gear mods available in 2025. Though it was quite an involved project, it’s safe to say that my time was well spent, and the end result is something my childhood self would’ve been astounded by.
All the Best Game Gear Mods
I simply could not skimp in any area when building this ultimate Game Gear, so I went with all the premier parts and mods, both inside and out. First things first, I nabbed a donor console, but only for a few crucial elements. Since most of the parts in the build are aftermarket, I only needed to extract the CPU, cart reader, and link port from the motherboard. Everything else was completely brand new, making this a truly custom handheld.
Those old, salvaged parts are destined for a flashy new motherboard, namely the SYF Motherboard. Since the standard Game Gear motherboards are prone to capacitor problems and other issues, this removes the need for maintenance further down the road. SYF also provided a custom power board, which enables USB-C charging and allows for two lithium-ion batteries to be added to the console. Better yet, SYF also sent a custom audio board, along with two external speakers, which together enable stereo sound. The ultimate Game Gear would not be complete without SYF’s newest offering as well, the GGFM kit, an additional audio chip that enables FM sound for Master System games.
All these amazing boards would be wasted without a better screen, and on that front, the folks at High Score Tech Supply were kind enough to gift me the latest BennVenn screen kit for the best visuals possible. To add a bit of Switch-like functionality, they also hooked me up with an HDMI add-on for the kit, which makes it simple to display the Game Gear on a TV. Of course, I needed an appropriately awesome shell to house everything, so I teamed up with Retro Gear Customs to make my ideal shell, which turned out better than I could’ve hoped.
If you want to watch me assemble everything, check out my Ultimate Game Gear video on YouTube to see the entire installation from beginning to end. I really got down to the nitty-gritty with this build, and if you plan on creating a custom Game Gear of your own, it’s a good resource to reference. Like with several of my other ultimate builds, this required a lot of soldering work, precise board modification, and running wire. In my opinion, the hard work paid off, but I’ll let you be the final judge of that.
The Pros, Cons, and Features of the Ultimate Game Gear
I have fond, deeply nostalgic memories of the Game Gear, and this ultimate build brings all of those warm, fuzzy feelings rushing back. At first glance, the shell is a sight to behold and really brings the entire project together. It also sounds as good as it looks, thanks to the custom audio chip and stereo sound, but I was especially impressed by the GGFM kit. Playing Master System games with FM sound is a notable improvement over the default PSG sound, resulting in crispier tunes without all the static. I also can’t give enough credit to BennVenn for the fancy GGHD display, which comes with tons of cool features like picture centering, scanline filters, and more. Of course, when I’m not busy playing on the handheld screen, the video signal can be beamed to my TV of choice with the HDMI mod, though the audio itself only comes out of the handheld.
As far as negatives go, there are only a few that I can think of. The real stickler is the lack of TV audio on the HDMI mod, but there are a few other features I’d like to see implemented. It would also be cool to see an external controller mod, which would turn the Game Gear into a consolized system of sorts. Like I mentioned before, this was also a notably tough build, especially when it comes to transferring motherboard parts. Creating a build like this will also cost a pretty penny, as all the parts combined total over $300, but it’s a small price to pay if you have a deep love for the Game Gear like I do. Overall, this was a fun project to tackle, nostalgia and all, and a great opportunity to give some love to one of my favorite handhelds of all time.
