The Sega Saturn is definitely making headlines these days. Chinese modder TZMWX, already known for his portable creations based on the console, has just unveiled the Sega CDX2. This project pays tribute to the legendary CDX (known as the Multi-Mega in Europe), that ultra-rare hybrid console from the 1990s which combined the Mega Drive and Mega CD in a revolutionary portable form factor. This time, it’s a full Saturn that has been miniaturized into a compact CD player-style case.

A tribute to the original CDX

The original Sega CDX, released in 1994, remains one of the rarest and most sought-after consoles in Sega’s history. About the size of a portable CD player, it could even function as one and run on batteries. Its prohibitive price ($400 at the time) and limited production turned it into a mythical collector’s item.

The CDX2 takes this bold concept further by integrating a Saturn motherboard folded in half to drastically reduce space requirements. A Sony KSM-900 optical mechanism replaces the standard CD drive, while the case borrows its top shell from a Sanyo CD player.

A gradual evolution

The final version of the CDX2, unveiled in early February 2026, includes many improvements over the December 2025 prototype. The finished model features a built-in modchip, 1M/4M EXRAM for games requiring expansion cartridges, integrated memory storage, a small LCD screen, and a Panasonic 21700 battery for portable use. The modular case allows different functional modules to be added.

TZMWX kept several elements from the Sanyo CD player used as a base: the headphone jack, volume potentiometer, panel button functions, and the multi-function slot. He also added a 5-button joystick, an LCD port on the rear panel, and two integrated Apple speakers.

A one-of-a-kind piece

As with his previous creations (notably the Sega Uranus inspired by the Venus prototype), TZMWX remains firm: his builds are unique pieces intended for his personal use.

The modder generously shares his progress on Twitter, documenting each step and potentially inspiring other makers to attempt their own projects. The CDX2 is part of a broader celebration of the Saturn, a console experiencing a true revival thanks to an active homebrew scene and a passionate community.
