Binding of Isaac: Rebirth - Savegame parser

Upload your Binding of Isaac: Rebirth savegame file and I'll tell you some stats, as well as list missing items and achievements. To see an example, have a look at one of the recently uploaded savegames below.

Tested with savegame format produced by BOIR versions 1.04x and 1.05. Your savegame should start with the string ISAACNGSAVE06R.

Caution: Contains spoilers! All characters, items, achievements and bosses are listed.

This project has recently (mid 2023) been rewritten in Python. Please contact me if there are any problems.
