Binding of Isaac Savegame Analyzer

The basic goal is to be able to output the status of a BoI savegame, regardless of the format (Rebirth, Afterbirth, Afterbirth+, ...).

The important parts are to focus on fields that are not easily checkable in game. For example, missing items and achievements only show up as a ? in game, which can make it hard to determine which ones are still needed. Boss progress is easily trackable on the sticky note for each character, which makes it less of a priority. Eventually, the full format should documented.

Formats

The format is listed as "binary offset(length): what is at the offset"
