A stock Game Boy in 2026 is hard to go back to. No backlight, scratched screen lens, faded buttons, mushy membranes. The hardware is solid — the screen and shell are what aged badly.
Game Boy modding fixes all of that. An IPS screen turns a dim, unlit display into something gorgeous. A new shell makes it look brand new. A USB-C mod kills the proprietary charger. These mods are affordable, well-documented, and — depending on what you pick — range from zero soldering to a Saturday afternoon project.
This guide covers every major mod type, which Game Boy models to mod, where to buy kits, and how hard each mod actually is.
Which Game Boy Should You Mod?
Not all Game Boys are created equal as mod platforms. Here is how they stack up:
| Model | Screen Mod Options | Shell Availability | Mod Difficulty | Best For |
|---|---|---|---|---|
| Game Boy Advance (AGB-001) | Excellent — FunnyPlaying IPS v2/v3 | Tons of options | Beginner-Intermediate | Best overall mod platform |
| Game Boy Advance SP (AGS-001/101) | Good — IPS kits available | Moderate options | Intermediate | USB-C mod + IPS combo |
| Game Boy Color (CGB-001) | Good — IPS kits, Q5 OSD | Good selection | Intermediate | Nostalgia + color games |
| Game Boy Pocket (MGB-001) | Good — IPS kits available | Moderate options | Intermediate | Compact form factor |
| Original Game Boy (DMG-01) | Good — IPS and backlit options | Great selection | Intermediate | The iconic look |
Best first mod project: The GBA (AGB-001). The FunnyPlaying IPS v2 kit is well-documented, the shell swap is easy, and the result is dramatic. It transforms a washed-out, unlit handheld into something that looks and plays better than most modern retro handhelds.
IPS Screen Mods — The Biggest Upgrade
An IPS screen mod replaces the original reflective LCD with a modern backlit IPS display. The difference is night and day. You go from squinting under a lamp to a vibrant, bright, crisp display that works in any lighting.
This is the single best mod you can do to a Game Boy. Everything else is cosmetic. This one changes how you play.
Game Boy Advance (AGB-001)
The GBA has the best IPS mod ecosystem. FunnyPlaying dominates this space.
- FunnyPlaying IPS v2 — The most popular kit. Drop-in replacement, minimal shell trimming required, brightness controls via touch sensor or button combo. Affordable and widely available.
- FunnyPlaying IPS v3 (Laminated) — The premium option. Laminated display bonded closer to the lens for better viewing angles and a more “integrated” look. Slightly more expensive, same installation difficulty.
- Retro Pixel IPS — Alternative to FunnyPlaying. Similar quality, different brightness control method. Good option if FP is out of stock.
Difficulty: Beginner-Intermediate. The screen connects via ribbon cable to the existing connector. Some shell trimming is required (a few plastic tabs with a flush cutter). No soldering required for basic installation. Optional soldering for brightness control wires.
Cost: $30-55 for the IPS kit. Plus a new shell if you want a clean look ($8-15).
Game Boy Advance SP (AGS-001 / AGS-101)
- FunnyPlaying IPS kit for GBA SP — Replaces the original screen. The AGS-001 (frontlit) benefits massively. Even the AGS-101 (backlit) sees improvement with a modern IPS panel.
Difficulty: Intermediate. Tighter space inside the SP shell. Ribbon cable routing is more delicate. Soldering typically required for brightness control.
Game Boy Color (CGB-001)
- FunnyPlaying Q5 IPS with OSD — The Q5 (retro pixel) display with an on-screen display menu for color palettes, brightness, and pixel effects. This is the premium GBC mod.
- Standard IPS kits — More basic, still a massive upgrade from the original unlit screen.
Difficulty: Intermediate. Shell trimming required. Soldering needed for full feature access (touch sensor, OSD controls).
Game Boy DMG / Pocket
- FunnyPlaying IPS kits — Available for both the original DMG and the Pocket. Same concept: modern backlit display replacing the original.
- Backlight kits (older approach) — Cheaper option that adds a backlight behind the original screen rather than replacing it. Lower quality than IPS but simpler to install.
Difficulty: Intermediate. The DMG has more internal space (easier to work with). The Pocket is tighter.
Shell Swaps — Easiest Mod, Biggest Visual Impact
A shell swap gives your Game Boy a fresh look with zero technical skill. No soldering. No cutting. Just unscrew, transplant the internals, screw back together.
What Is Available
- Clear / transparent shells — See-through in every color. The most popular choice. Clear purple, clear blue, clear smoke, etc.
- Solid color shells — Matte or glossy finishes. Clean, factory-fresh look.
- Prestige shells — Higher-quality aftermarket shells with better texture, tighter tolerances, and premium feel. RetroSix and Boxy Pixel make prestige options for various models.
- Custom / limited edition — Glow-in-the-dark, color-changing, metallic, UV-reactive. The community gets creative.
Where to Buy Shells
| Retailer | Quality | Price Range | Notes |
|---|---|---|---|
| FunnyPlaying | Good | $8-15 | Best value. Wide color selection. |
| RetroSix | Premium | $15-30 | Prestige line has excellent build quality. |
| Hand Held Legend | Good-Premium | $10-25 | Curated selection, US-based. |
| Retro Modding | Good-Premium | $10-25 | Canadian, good selection. |
| AliExpress | Variable | $3-10 | Cheapest option. Quality varies. Slow shipping. |
Tip: If you are doing an IPS screen mod, buy a shell designed for IPS kits. These have the necessary cutouts pre-made so you do not need to trim anything.
Difficulty
Zero. If you can use a screwdriver, you can swap a shell. The GBA uses a tri-wing screw (special screwdriver required, included with most kits). Takes 15-20 minutes.
USB-C Charging Mods
The GBA SP charges via a proprietary Nintendo barrel connector. In 2026, this is annoying. USB-C mods replace it with a standard USB-C port so you can charge with the same cable as everything else.
Options
- Drop-in USB-C boards — Small PCBs that replace the original charging port. Available from Hand Held Legend, RetroSix, Makho, and others.
- USB-C with battery indicator — Some boards add LED battery indicators or faster charging.
Installation
Difficulty: Intermediate. Requires soldering 2-4 wires to the main board. Some boards need minor shell trimming to fit the USB-C port. Not a first mod, but very doable if you have basic soldering skills.
Cost: $10-20 for the USB-C board.
Which Models?
Primarily the GBA SP — it is the model with the rechargeable battery and proprietary port. The original GBA and DMG use AA batteries and do not benefit from this mod (though rechargeable battery packs with USB-C charging exist as separate mods).
Button and Membrane Replacements
Old Game Boy buttons get sticky. Membranes lose their snap. Replacing both takes 10 minutes and makes the handheld feel factory-new.
What to Replace
- Button sets — Aftermarket buttons in every color. Silicone, plastic, or metal options. $3-8 per set.
- Silicone membranes / contact pads — The rubber pads under the buttons that make contact with the circuit board. These degrade over time and cause mushy or unresponsive inputs. $2-5 per set.
- Shoulder button replacements (GBA/SP) — The L and R tactile switches wear out. Replacement switches are cheap and solderable.
Difficulty
Buttons and membranes: Beginner. No soldering. Just open the shell and swap them.
Shoulder button switches: Intermediate. Requires desoldering the old switch and soldering the new one. Small components.
Audio Mods
Speaker Upgrades
Original Game Boy speakers lose volume and clarity over time. Drop-in replacement speakers restore full sound. Available for all models, typically $3-5. No soldering — they connect to the same pads.
Amp Kits
CleanAmp and similar audio amplifier boards boost the Game Boy’s output volume and clarity significantly. Great if you play without headphones. Requires soldering.
Difficulty: Speaker swap = Beginner. Amp kit = Intermediate.

FAQ
Which Game Boy model is best for a first mod?
The GBA (AGB-001). Plenty of internal space, the FunnyPlaying IPS kit is foolproof, and a shell swap + IPS takes under an hour with no soldering required.
Can I combine multiple mods?
Absolutely. The most common combo is IPS screen + new shell + new buttons + new membranes. You are rebuilding the entire handheld around the original motherboard. Many people do all of this in one session.
Should I buy a broken Game Boy to mod?
Good strategy. Broken Game Boys with cracked screens or corroded battery contacts are cheap on eBay. If the motherboard works, you are just replacing everything else anyway. Test it before buying if possible.
Are aftermarket shells as good as the originals?
Most are close. FunnyPlaying and RetroSix shells have good fit and finish. The cheapest AliExpress shells can have rough seams or slightly off tolerances. Premium options from Boxy Pixel (aluminum) are genuinely nicer than the original plastic.
How much does a full GBA mod cost?
A typical full mod — IPS screen, new shell, new buttons, new membranes, new screen lens — runs about $50-70 in parts. Plus $10-15 in tools if you do not already have them. Plus the donor Game Boy itself.
Modding a Game Boy is game preservation at the hardware level — keeping original consoles alive and playable for decades to come. The hardware was built to last. The screens and shells just needed an upgrade.
