The Wondermega (ワンダーメガ) is a combined Sega Mega Drive and Sega Mega-CD unit created by Victor. It was initially released in 1992 as the first "combo" unit of its kind, seeing a North American release as the X'Eye in 1994.


Four models of Wondermega were produced between 1992 and 1994, all sharing a similar set of features albeit with different case designs. Primarily the Wondermega serves as a high-end Mega Drive and Mega-CD unit, with composite and S-Video television outputs built into the unit in addition to the standard RF. The original 2 models even featured a motorised pop-up disc tray.

Also included is a digital signal processor (DSP) for audio enhancement, a MIDI output and two microphone inputs for use as a karaoke machine.


There were several models of the Wondermega, though sales never reached that of the standard Mega Drive or Mega CD units, due to the Wondermega's substantial price. All of them have the TMSS.

Wondermega, Victor RG-M1 Model

The first Wondermega model, the RG-M1 is as described above, shipping with Wondermega Collection, a compilation disc that includes Quiz Scramble, Flicky, Pyramid Magic and Paddle Fighter. However, at ¥82,800 the system was priced well above the cost of a combined Mega Drive (¥21,000 at launch) and Mega-CD (¥49,800 at launch, totalling ¥70,800 (although prices for both would have dropped significantly by 1992)).

Victor released a pair of matching speakers - the "Wonder Sound" (RG-SP1), for ¥22,000 at around the same time.

Wondermega, Sega Model

By the end of April 1992 Sega released their own Wondermega model which retailed for ¥3,000 less. This version is basically identical to the Victor RG-M1, but the sticker that is seen next to the Wondermega logo is removed and the Victor logo near the disc tray is replaced with the Sega logo.

Wondermega M2, Victor RG-M2 Model

Sweeping changes were made in the RG-M2 model, released by Victor in 1993. The DE-9 controller ports were moved to the back, and in their place, an infrared receiver. M2 wireless controllers are very different in design from Sega's models and feature six buttons. The RG-M2 also employs numerous cost-cutting measures, resulting in a slightly smaller unit with a sleeker design.

While Sega 32X compatibility is maintained, the design means that the disc drive door cannot be opened completely with a 32X attached. Victor offered a "32-bit upgrade service" for ¥5,000, which would see the lid replaced with a new design capable of opening when a 32X is attached. The result partially obscures the disc drive internals but largely alleviates the problem. Curiously Victor maintained this service until 2013 - 20 years after the system's debut.


During the spring of 1994, JVC released the Wondermega RG-M2 as the X'Eye in the United States, albeit with several features removed. The S-video connector was dropped in favor of the 9-pin AV port used by the Mega Drive II (although some X'Eyes lack this) and the wireless controllers were dropped, with standard 9-pin controller ports in place of the M2's infrared receiver.

Very early X'Eye consoles lack the aforementioned 9-pin AV port, and so cannot function with a 32X. Most X'Eye consoles work with the Sega 32X add-on, although similarly to the M2 above, the 32X blocks the lid of the disc drive from opening completely (potentially causing issues with some Sega Mega-CD 32X games which require discs to be swapped).

The X'Eye was packaged with Prize Fighter, Compton's Interactive Encyclopedia and a Karaoke CD that included the songs Achy Breaky Heart and Two Princes.
