v1.1 (#16)

* 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

 # Description
 
-This software will help you to easily unpack and repack Nintendo DS roms, but **IT REQUIRES SOME KNOWLEDGE!**

+A typical NDS ROM consists of the following sections:
 * Header
 * ARM9 Binary
 * ARM7 Binary
@@ -27,38 +27,29 @@ Basically an NDS software is composed of the following sections:
 * Icon/Title Logo
 * FAT Files (The actual files used by the software, like Graphics, Music etc.)
 
-With NDSFactory you can extract these sections, modify them using your prefered way and the rebuild the rom with your edited sections.
+NDSFactory allows you to extract these sections, modify them as needed, and rebuild the ROM with your edited sections. If modified sections are larger than the original, you must specify their new physical address and size in the header. **Ensure that sections do not overlap and remember to patch the FAT.BIN if necessary.**
-If the modified sections are bigger than the original ones, you can specify their new physical adddress and size in the header: if so, **make
-sure that they DON'T OVERLAP, and remember to PATCH THE FAT.BIN** (more on this later).
 
-**This software will be particularly useful if you want to mod your games or write a trainer for them.**
+This tool is particularly useful for modding games or writing trainers.

 ## Unpacker Tab
-In the upacker tab you can load your Nintendo DS software (.nds) and then you can extract the rom sections.
+In the Unpacker Tab, you can load your Nintendo DS software (.nds) and extract the ROM sections, including individual FAT files. Take note of the original address of the FAT files, as you will need this value if you alter the addresses and sizes of the sections.
-Please note the Original Address of the FAT Files, you will need this value later if you are going to alter the addresses and size of the sections.
 
 **You can then do what you want with these sections (inject code, apply patches etc.)**
 
 ## Packer Tab
-In the packer tab you can re-create an .nds file using your edited sections. If your sections are bigger than the originals, you have to edit their addresses and size (in the header). **Make sure that the addresses don't overlap, or the final rom will be broken**. If you are repacking edited sections, and the FAT Files Address is different than the original one, **make sure to patch the FAT (fat.bin)**: the FAT is a list of absolute addresses (representing each file start adddress and end andress), so you need to update them (you can easily do this using the FAT Patching Tab).
+In the Packer Tab, you can recreate a .nds file using your edited sections. If your sections are larger than the originals, you must update their addresses and sizes in the header. Ensure that the addresses do not overlap, or the final ROM will be broken. If you repack edited sections and the FAT files' address is different from the original, you must patch the FAT (fat.bin). The FAT contains absolute addresses representing each file's start and end addresses, so you need to update them accordingly (use the FAT Patching Tab for this).
 
-## Fat Patching Tab
+## Fat Tools Tab
-In this tab you can easily patch the FAT section (fat.bin). You have to do this only if the FAT Files (fat_data.bin) final address is different than the original one.
+In this tab, you can patch the FAT section (fat.bin). This is only necessary if the FAT files' final address (fat_data.bin) differs from the original. Patching the FAT is straightforward: load your fat.bin, and fill in the original and new addresses of fat_data.bin. This will produce a patched fat.bin for use in the packing process.
-Patching the FAT is easy, all you have to do is load your fat.bin, and fill the original address and the new address of fat_data.bin. This will produce a patched fat.bin that
-you can use in the packing process.

-# Know Limitations/Possible Future Featurs/Bugs
+* Add support for ROMs with overlays.
+* Add support to rebuild a new fat_data.bin and fat.bin from a set of files inside a directory.

+If you find a bug, feel free to open an issue or submit a pull request :)
-* Add support to decode FAT Files (extract single files one by one)
