 ### Current state
 
-- :tada: The build is shiftable! You can make any code or asset additions/modifications you like, and most aspects of the game will continue to function.
-- Assembly code [extracted, disassembled, and somewhat categorised](./asm/)
-- All libraries decompiled to C or referenced from `agbcc`
-- Most aspects of the game, including all interactables, have been decompiled to matching C code. Most have not been fully documented, but major functions are.
+- :tada: The build is 100% from C files with [~80 functions which currently don't match](./asm/non_matching)
+- All assembly code extracted, disassembled, and decompiled by hand to their C equivilent
 - All songs have been extracted, and documented as [matching MIDI files](./sound/songs/midi)
-- All sprite animation frames have been extracted to PNGs and are used to build the matching rom
-- Most tilemaps (backgrounds) have been documented and had their tiles extracted
