Aeon Genesis (or AGTP) is a ROMhacker group popular in the Cave Story community for its English translation of Cave Story, which was originally made available by Pixel exclusively in Japanese. AGTP was in contact with Pixel during the development of the translation, likely so they could confirm the meanings of ambiguous pieces of text. This translation is aptly called the Aeon Genesis translation. The only other translation in common use is the one created by Nicalis for its various ports and remakes.
