Next thing im workin on for a while now, is an ffm file viewer for Final Fantasy X. There was once a guy out there, yaz0r, that had the incredible skill to revert the format from the PS2 game executable and wrote the well know FFXViewer tool. Unfortunately he deleted all his stuff and the research about it. So I basically took his tool and decompiled it to pseudo C from asm, to get the structure of the file for it. put my research so far on SVN repo too
