WonderGate

The WonderGate, also known as MobileWonderGate, is a communication adapter kit that had been developed for WonderSwan handheld consoles.

Features
The main device allows the WonderSwan console to be connected to a mobile phone through the accessory port. A separate cartridge contained an e-mail client and browser that supported HTML 3.2 and allowed downloading of 32KB mini-games. Some titles, such as Digimon Adventure 02: D1 Tamers, allowed the addition of features through downloadable content. Other titles, such as Mobilesuit Gundam MSPlatoon.com and Super GPS Pac-Man, were announced with WonderGate support, but were cancelled before release.

Internet connectivity was provided by NTT Docomo's mopera (Mobile Operation Radio Assistant) service and J-Phone-compatible handsets.

Releases
The MobileWonderGate was announced by Bandai on June 23, 2000 and was released on July 14, 2000. On October 31, 2001, Bandai announced that online service for WonderGate-connected games was being terminated. The remainder of online game services ended on March 31, 2003, though the e-mail and browser software continued to function.
