tool for doing isaac daily run :P

README.md

this is a python 3.8+ script that automatically toggles EnableDebugConsole... because to do daily run not only do you have to turn off all mods but also you have to disable the debug console.

(NOTE: ONLY FOR REPENTANCE ON WINDOWS!!!1!)

put this file literally anywhere on your device and it should work... i hope.

it finds the options.ini file in your $USERPROFILE/Document/My Games/Binding of Isaac Repentance/ directory and either

• creates a new options.ini with a single line EnableDebugConsole=1, or
• toggles the value of EnableDebugConsole in the preexisting options.ini file (by toggling i basically mean 0 turns into 1, and 1 turns into 0)

if you don't have any line that starts with EnableDebugConsole, then this script will append EnableDebugConsole=1 to the end of your file.

running this script changes options.ini upon success, although a backup can be found at options_backup.ini. (if options_backup.ini already exists, though, it is overridden without warnings.)
