Merged in gba-gen3multiboot

I originally cloned this repo from gba-link-cable-dumper so this commit
is merging in the "changes" from gba-gen3multiboot even though I really
already applied everything myself. Also changed the output binary name,
and removed the unused dependency on libfat.

Todo: rewrite README.

-# GBA Link Cable Dumper
-A GC and Wii Homebrew App to get GBA BIOS, ROMs and saves via the GC GBA Link Cable.  
-Save Support based on SendSave by Chishm.  
-GBA BIOS Dumper by Dark Fader.  
+# GBA Gen3 Multiboot
+A GC and Wii homebrew app that sends a binary to the GBA using the different multiboot protocol used by the third generation of Pokémon games (Ruby, Sapphire, Emerald, FireRed, LeafGreen).
 
 # Usage
-Just have a GC Controller in Port 1 and a GBA without a game inserted or aborted game launch by holding select+start in Port 2. 
-The bin, gba and sav files dumped will be placed in a folder called "dumps" on your main device (SD Gecko on gamecube and SD/USB on Wii). Please note that dumping GBA ROMs can take a long time (32mb takes about 48 minutes) because of the cable protocol limitations, a estimation will be displayed on screen before you dump it as a reference.
+Have a GC Controller in Port 1 and a GBA with Gen3 game in Port 2.  
+Put your payload code to do some interesting stuff with the Pokémon game you have in `gba` dir. Example code that warps the character to the Hall of Fame, adding a Bad Egg if the save has no Pokémon provided.  
+Recompile, send to Wii or GC, turn on your GBA, hope that your code runs after the initial copyright screen of the game.  
+(Code execution rate is for some reason not 100% reliable, PR to fix would be greatly appreciated. Sometimes KeyC derivation fails, sometimes GBA ignores the sent multiboot image, could be due to failure of a few different sends)
+
+# Acknowledgements
+Thanks to FIX94 for your multiboot game dumper, which the multiboot code is loosely based on (differences in crypto & protocol...)  
+Without it, this would have taken longer to do than the 2 days or so that it took.
