Cave Story is a fun little freeware Japanese game.
An English translation patch was created by AGTP for the PC version of the game. A Macintosh version of the game was created, but the PC-patching application didn't work with it, so it required manual patching.
This is an automatic Macintosh version of the patch which will also translate the room location names, which the manual method did not do.
With the release of a Universal Binary of Cave Story, the patch needed to be updated as well. This patch no longer works with older versions of the application. If you have an older version of the application you need to patch, the old version of the patch is available here.
