Topic :: Poem

The Poem element in the Celeste savefile denotes a list of string elements, each being an abbreviation for the game's journal (referred to in the savefile as poem).

Each chapter has a 1-2 letter abbreviation, and another abbreviation followed by r for remix, which is what the savefile uses to refer to B-Sides and/or C-Sides.

A player's savefile poem might look like this:

<Poem>
  <string>fc</string>
  <string>cr</string>
  ...
</Poem>

Which means they have both Chapter 1 and Chapter 3's Crystal Heart.

os	2A - Old Site	Resurrections
osr	2B - Old Site	Black Moonrise
cr	3A - Celestial Resort	Scattered and Lost
crr	3B - Celestial Resort	Good Karma

tsr	7B - The Summit	No More Running
mc	8A - Core	Heart of the Mountain
mcr	8B - Core	Say Goodbye
fw? ll?	9 - Farewell	Empty Space

While Chapter 9 is assumed to be either fw (Farewell) or ll (LostLevels), it does not appear in the `Poem` upon collection, most likely because this heart is fake and shatters during the in-game cutscene.
