San Jose-based Silicon Xtal Corporation, an integrated circuit and passive component manufacturer, appears to be working on a console specializing in Adults Only-rated games and mature content.

The company registered the name "Sex Box" in the U.S., describing the concept as a "video gaming system console comprised of computer hardware with unique user controls which plays interactive Adult Only rated (AO) video game software titles, and has proprietary software and firmware that provides access to associated AO content and entertainment in all other digital forms."

Those other forms of Adults Only content and entertainment include "audio, video, HDTV, DVD, online, gaming, social network, webcams, video on demand, downloading, movie rentals, purchases, stores, advertising, interactive adult communities, massive multiplayer online games, and emerging markets in one or any combination of these and more as technology evolves."

SXC has some experience working with consoles, though certainly not at a level comparable to Sony, Nintendo, or Microsoft. The manufacturer says products like the iPhone/iPod, MacBook, iMac, Nvidia graphics cards, and Xbox 360 use its circuit designs. Being a partner to the company, I imagine Microsoft would not appreciate the name SXC's chosen for its console.

It's hard to imagine a market for an only Adults Only console, as there really aren't many games with that rating in the U.S.. Most developers that receive an Adults Only rating for their games tone down their content -- as was the case with Manhunt 2 and The Punisher -- so that retailers won't refuse to put the releases on their shelves.

As far as I know, the only released console game with an Adults Only rating is Grand Theft Auto: San Andreas due to its Hot Coffee minigame, and Rockstar eventually re-released an M-rated version (and a "Cold Coffee" PC patch) for that, too.
