Persona 2: Innocent Sin is the missing chapter of the Persona series. Die hard Megami Tensei fans know this and have been craving to play the first half of Persona 2 in English.
Thankfully, Gemini is hard at work on the job. He (she?) has a blog discussing the trials of the fan translation with status updates about how it’s progressing. From the screenshots alone it looks solid. However, no one except Gemini has played it since a patch is currently unavailable to the public. Keep an eye out the blog though because the coveted English code could spring up at any time.
