So, to catch up, back in May Dreamcast Live reported that Mobile Suit Gundam: Federation vs. Zeon is back online. This includes both the original and updated DX versions.
Inada-s reverse-engineered the server for the Dreamcast and PlayStation 2 versions of the game. The re’d server was originally intended for use in an emulator, but Shuouma adapted the code to work on real hardware as well.
This is the twenty-fourth multiplayer game to make it back online (including the unofficially released PBA Tour Bowling 2001 and Internet Game Pack as well as Sega Swirl, which is played through e-mail). It is also the first Japanese-exclusive title to make it back online.
Keep an eye on the Dreamcast Live online games page to see what games come back online next.
