I was bored and at the moment only know Java. So I decided to program a character editor in Java.

For this to work, at the moment you just need to place the file in the right place.

For Windows typically:
C:/Program Files (x86)/Steam/SteamApps/common/The Binding of Isaac Rebirth/resources/

For Mac, typically:
~/Library/Application Support/Steam/SteamApps/common/the binding of isaac/The Binding Of Isaac.app/Content/Resources/resources/


Works on mac and windows and linux.

Have fun!


P.S. Would love if someone could help with images and graphics. I'm more of a programmer and not a graphics person.
