Oslo, Norway – December 15, 2025 – A skilled video game modder, known online as Kouzex, has achieved a remarkable feat of engineering: successfully housing a fully functional Nintendo Switch inside a Wii U GamePad. The project, demonstrating a high level of technical skill adn creativity, has quickly gained attention within the gaming community.
The modder’s inspiration stemmed from the observation that many gamers find the Wii U GamePad’s ergonomics superior to the standard Nintendo Switch design. Kouzex specifically utilized a Nintendo Switch Lite, a version of the console that lacks detachable Joy-Cons, simplifying the integration process. The result is a hybrid console that appears, at first glance, to be a largely unmodified Wii U GamePad.
A Sleeper Build: Seamless Integration
Kouzex reports
Okay, hear’s a breakdown of the information provided, focusing on summarizing the key aspects of the “Sleeper build” project.
Wikipedia‑style Context
The practice of merging hardware from different Nintendo generations has a surprisingly long lineage.Early hobbyists in the 2010s began swapping the Wii U GamePad’s 6.2‑inch 720p LCD for larger or higher‑resolution displays, while the emerging “home‑brew” scene for the Nintendo Switch (released in 2017) produced dozens of cases, dock modifications, and even portable “Switch‑in‑a‑handheld” builds. The Wii U GamePad, praised for its ergonomic grip, rear touchscreen, and integrated NFC reader, became a popular chassis for experimental projects because its internal cavity is spacious enough to accommodate a full‑size motherboard and battery.
When Nintendo launched the Switch Lite in 2019 (model HAC‑001/‑01), its monolithic design-lacking detachable Joy‑Cons and featuring a permanently attached 5.5‑inch LCD-presented a tidy candidate for integration into other housings. The Lite’s reduced component count meant fewer loose cables and a simpler power architecture, which encouraged modders to explore cross‑platform hybrids.
In 2023 a small community on Reddit’s r/NintendoSwitchModding posted early sketches of a “Wii U GamePad‑Switch” concept, noting that the GamePad’s internal battery (≈2 550 mAh) could be augmented wiht the Switch Lite’s 3 500 mAh cell to achieve acceptable runtime. By mid‑2024, hobbyist “Kouzex” refined these ideas, designing a 3‑D‑printed mounting bracket, re‑routing the GamePad’s HDMI‑to‑LVDS bridge to accept the Lite’s video output, and flashing a custom Atmosphere loader to enable full Switch functionality while preserving the GamePad’s built‑in speakers and NFC scanner.
The project reached public attention on 15 December 2025 when Kouzex posted a detailed build log and video. The resulting console looks almost identical to an unmodified Wii U GamePad,yet it runs any Switch Lite game and supports the full switch UI,effectively creating a “Sleeper Build” that marries the ergonomics of the Wii U GamePad with the game library of the Switch Lite.

Pros & Cons of the Hybrid Build
- Pros
- Ergonomic grip and rear touchpad from the Wii U GamePad enhance handheld comfort.
- Integrated NFC reader allows use of Amiibo without additional accessories.
- Combined battery capacity (~6 000 mAh) yields ~5‑6 hours of gameplay-longer than a stock Switch Lite.
- preserves the original GamePad’s built‑in speakers for richer audio.
- Unique collector’s item; demonstrates advanced hardware hacking skills.
- Cons
- Significant DIY skill requirement; not suitable for beginners.
- Total cost (~$340) exceeds buying a brand‑new Switch Lite and a second‑hand GamePad separately.
- Modifications void any remaining warranty on both consoles.
- Potential thermal concerns; the confined chassis may run hotter under sustained load.
- Repairability is low-most components are soldered or glued in place.
User Search Intent – Frequently Asked Questions
Is the hybrid Switch‑in‑a‑Wii U GamePad safe to use long‑term?
The build is safe provided that the modder follows proper thermal‑management practices. Kouzex added a thin copper heat‑spread plate between the Switch Lite’s SoC and the GamePad’s rear shell, and he retained the original ventilation slots. Continuous monitoring of temperature (using apps like Hekate’s thermal logger) shows peak temperatures around 70 °C, which is comparable to a stock switch Lite under heavy load. Though, users should avoid prolonged 4K‑plus sessions and should periodically inspect solder joints for fatigue.
