Hi there. I've heard about GemRB and I would need to create new raw dataset for to be used FREELY (contrarily to most of actual production, which actually violates bioware copyrights on these games) for creation of new "mods", but i'd rather say, new adventures.
These would include sprites (images and animations) for items, characters, creatures, maps (actually map elements to be merged)
since gemrb is capable of using dataset already done for BG, IWD etc, my question is: where do I find specifications for data used by BG2 & IWD2 infinity engines?
