Who is saying they're finished?
According to Marks worklog it sounds like he considers the documentation as-is to be pretty much final.
Anyway, I agree, the docs need to document the classes -_- I made a OOPified bank class that calls all the bank functions, only to find out the TBank class is already oopified and the standard functions actually call the methods. Now I'm working on adding stuff like PokeString, PokeArray, PokeBit, PokeData...
