I'm trying to parse a .dat file, but it goes wrong [somewhere].
I've also compared my code with RME's sources and somewhat copy-pasted a whole bunch of it, yet it still messes up.
(yeye huge mess below)
It just messes up while reading the bytes.
About 2394712389523457812345789 popups that a certain byte is unknown;
So I basically conclude I'm missing some bit of parsing.
Loading the version and items/outfits etc. count works correctly.
Weird, however, is that whenever I just ignore everything that goes wrong, I get some kind of successful sprite output. However, several sprites are missing, the numbers are incorrect, etc.
Anyone has any idea what might be wrong?
