* First step in implementing FAT file decoding : brute-force extraction without FNT lookup. The FAT alone contains enough information to extract every file in a folder chosen by the user. However, reference to the file name table (FNT) is needed to restore the files' names and the directory structure (and avoid dumping useless data that may be left over in the data section). This commit only implements the dumping of all data by incrementing through the FAT and writing every section marked by a FAT range into a separate file, giving them incremental names. The next commit will use the FNT to name them properly. * Proper FAT decoding : FNT lookup and directory structure Code comments explain the algorithm (which was understood thanks to the wonderfully simple "FNT-Tool" script at : https://github.com/RoadrunnerWMC/FNT-Tool) ; the implementation is more or less a C++ port of the Python code. Everything may still be a little dirty, but it works ! * Updated README! * Updated README! * MINOR compliance modifications - Removed extra entry in .gitignore - Removed superfluous debug inclusions - Replaced magic values by preprocessor macros Co-authored-by: rblard <rblard@enseirb-matmeca.fr>
