Mega Man Battle Network 2:
Translation Revision

This is a patch for Mega Man Battle Network 2, as well as a mod for the Legacy Collection version, that aims to generally improve the quality of the English script while mostly keeping to the original localization. It fixes and improves many lines, the result of a more or less full script comparison with the Japanese text.

In general, this project:

More details on the types of changes can be found in the included Readme.

* Disclaimer: While this aims to curtail culturally-offensive dialogue from the original translation, certain things are just part of the plot or otherwise beyond the reach of a script edit. Thus, be aware there are still some cultural stereotypes and xenophobic undertones (as you may know if you've played the game before).

This project has no affiliation with Capcom and does not distribute copyrighted material, only patches.

This version is a patch for the original North American GBA release of Battle Network 2. You will need your own clean dump of the game ROM to apply the patch to. The ROM from the Virtual Console release should also work.

(Also available on Nexus Mods)

This version is a mod for Mega Man Battle Network Legacy Collection Volume 1. I can confirm it works on the PC release; other platforms may also be supported if ChaudLoader has support for them.


The mod simply replaces a few asset files, so it can also be installed manually without ChaudLoader if necessary.
