Rockman EXE Operate Shooting Star is a 2009 port of Mega Man Battle Network that added the ability to control Mega Man Star Force, as well as a side scenario involving him, but it was never released outside of Japan. Fans have been hard at work translating the game, and the translation project has finally been completed.
The game is now titled Mega Man Battle Network: Operate Star Force, and is mostly based on the English script for the first Mega Man Battle Network . However, many mistranslations and typos have been fixed, as well as other minor localization changes.
The one thing that wasn’t translated was the Download Play client for the ‘Star Colo’ feature, as the Nintendo DS/3DS will not run modified Download Play clients. However, the rest of the game is fully in English.
You can find a link to the translation project, which has the download link, here.
Rockman EXE: Operate Shooting Star is available for Nintendo DS.
