Fire Emblem Rebirth is a forum hack of the Japanese version of Fire Emblem 11: Shadow Dragon. The changes are really minor but enough to be called a hack: stats, growths, and names of some units have changed. It is patched with an incomplete translation of the japanese version of Shadow Dragon and thus not very good. The idea was that this would be the first Shadow Dragon hack to be released and little else.

The list of specific changes were lost, unfortunately. The game can be played by transferring the files inside and putting them inside an unpacked folder of the Fire Emblem Shadow Dragon (J) ROM, recompiling the game with the updated files, and then using a Nintendo DS emulator, such as No$GBA, to play the game.

The creator is Blazer, also known as "Fire Blazer" and "Keriku", who made the hack for his forum members (where members replaced characters with new names and gave different stats and growths for the characters). He also made the Nightmare Modules for the Japanese, European, and North American versions of the game.
