Phoenix Wright: Ace Attorney - Justice for All, released in Japan
as Gyakuten Saiban 2, is a point-and-click adventure video game
developed and published by Capcom for the Nintendo DS video game
console. It is the sequel to 2005's Phoenix Wright: Ace Attorney.
It was released in Japan on October 26, 2006 and in North America
on January 16, 2007. The game was also released in Europe on March
16, 2007. The Japanese release is region free, and features a
Japanese/English language toggle at the main menu.
Phoenix Wright: Ace Attorney - Justice for All is an updated port
of the Game Boy Advance game Gyakuten Saiban 2. It features touch
screen control like Phoenix Wright: Ace Attorney did, but does not
have any new cases.
A PC version under the title Gyakuten Saiban 2 PC was released by
the Japanese company SourceNext in March 31, 2006. Similar to the
PC port of the first game, this is an emulation of the original
Game Boy Advance version to be played on Windows based PCs, rather
than an enhanced remake like the one that was released afterwards
for the Nintendo DS. Again, it was only released in Japan.
