I wouldn't get too excited yet, I don't have an abundance of time anymore, and at the minute I'm just writing loaders for all the different Apoc resources. Currently I can load sounds, fonts, and the PCXs (which I didn't even have to write any code for).
One of the problems I've got, is that I can't find any information what-so-ever on any of the formats. PCKs don't seem to load in the UFO tools, so I'm assuming the format has changed.
Somebody must know how the PCKs are formatted, because there have been graphic mods (unless I just have a bugged version of PCKview?)
