The retro modding scene never ceases to amaze us. Over the last 12 months we’ve seen the Virtual Boy Console, the Boxy Pixel Custom Gameboy and the ArcadeBoy.

But now, the modder known as StonedEdge on YouTube has created a custom Nintendo Wii that looks exactly like the Gameboy Advance SP called the WiiSP.

His love for the clamshell Gameboy goes way back, and with the power of the Wii not only being able to play Wii games, but also the best Gamecube games too, Benjamin came to the mad conclusion that it would be fun to make the Wii console look like a Gameboy Advance SP.

He did just that.

The WiiSP looks and feels like an original Gameboy Advance SP that has a little too much junk in the trunk. Benjamin used a block of acrylic and then shaved it down using a CNC machine in order to get this look.

The bottom houses all of the goods, from the battery, to the motherboard to all of the buttons, analogue sticks and so on.

Around the device it features four shoulder buttons, USB-C, SD card to load your games, on/off, headphone jack, and a volume wheel. Once you pop open the WiiSP you will be greeted with a bunch of reassessed buttons that allow the device to shut.

There’s two analogue sticks, a DPAD, action buttons, two speakers, LEDs for battery signal, and start select buttons. What’s very interesting is that he has added shoulder buttons on the back that are pressure sensitive. Something that we rarely see in modded handhelds.


Benjamin showcases the menu system, and how the WiiSP operates. Mario Kart on the Nintendo wii has never looked so good, and the fact that you can snap the screen down and chuck a genuine Nintendo Wii in your bag is incredible.

He’s done a very impressive job, the 3D printed shell looks great quality, and so do the buttons. The analogue sticks themselves look like Nintendo Switch sticks too.

Benjamin has made this build completely open source, allowing other modders and even yourself to give it a try. You can click here to get a better insight into the WiiSP and how it was made alongside a guide on how to do it yourself.
