Flags are an organized system of tracking which choices the protagonist has made throughout their playing Undertale. These are found by opening "file0", an internal progress tracking file, with any text editor. There is space for 513 flags to be used, though only about X are in use currently. The flag with number n can be found in line n + 31 in the file com.tobyfox.undertale/file0.

List of flags
If a flag does not appear in the below list, it is unused – that is, it remains at 0 no matter what actions the player takes.

A bool value is either 0 or 1, where 1 represents true. An r. (range) value can be other numbers, and is by default 0 unless otherwise specified; a count is a specific type of range flag that increments every time the protagonist fulfills a requirement. All flags are defined with a numerical value.
