Content creator LCLDIY has a habit of building things that don’t need to exist, but probably should. His latest project turns a LEGO-inspired handheld shell into a working retro gaming display that’s deliberately oversized and oddly charming. Think Game Boy proportions, but blown up, and paired with a screen that tries to feel like a CRT without actually being one.
The goal wasn’t resolution or sharpness. It was softness.
Why Old Games Look Wrong on New Screens
Classic pixel art games were made for CRTs. Those displays blurred edges naturally through interlaced scanning and phosphor glow. Modern LCDs and OLEDs show every hard pixel boundary. The result is clean, but often ugly.
LCLDIY wanted a thin screen that could bring back that gentle blur and glow, without hauling around a glass tube from the 90s. His answer was an electroluminescent panel.
Electroluminescent Instead of LCD
Electroluminescent panels work by exciting phosphor material with an electric field. There’s no backlight and no pixel grid in the modern sense. When they light up, they glow. That glow softens edges in a way that feels immediately familiar if you grew up with CRTs.
For retro games, that glow does a lot of visual heavy lifting. Jagged pixels calm down. Flat colours feel warmer. It’s not accurate CRT emulation, but it lands in the same emotional space.
The Hard Part Was Driving the Display
The panel doesn’t accept HDMI or VGA. Instead, it expects raw signals like horizontal sync, vertical sync, clock, and data lines. That’s old-school territory.
LCLDIY explains that legacy “6550-series” graphics chips can generate the right signals, so he built a dedicated graphics card around that idea. To make it all work, he also created a modified BIOS with a custom resolution and burned it onto a ROM chip for the card.
The rest of the system is built around an Intel 845 motherboard, grounding the whole setup in early-2000s PC hardware that still plays nicely with low-level video signals.
A Giant Game Boy Shell
The electronics live inside a large Game Boy–style case inspired by a LEGO version of the handheld. LCLDIY modelled the shell himself and printed it on a resin printer over about a week.
After printing came sanding, painting, and assembly. Oversized buttons, bold decals, and thick plastic walls sell the toy-like look. It’s intentionally impractical. It’s big, chunky, and unmistakably Game Boy–shaped.
Limitations Included
The screen does what it set out to do. It glows, it softens the image, and it makes pixel art feel less harsh. But it’s also limited by the era it comes from. There’s no actual colour, and the display capabilities are modest by modern standards.
LCLDIY is upfront about that. This isn’t about perfection or specs. It’s about vibe.
Open Source, As Always
As with his other builds, all project files are shared as open source in the video description. Schematics, models, and firmware are there for anyone curious enough to dig in or build their own oversized, glowing Game Boy.
It’s unnecessary. It’s overbuilt. And it’s a great example of using old display tech to make retro games feel right again.
