Fixed a bug in AR cheat system, codes starting with 0x00 to 0x07 should work now as I tested this in ZTP and SA2,and most of the codes worked. One code in SA2 breaks dolphin now, and 1 code in ZTP messed up the graphics and breaks the game if trying to load a save game, else most codes work. Also SSMB codes work for me, there are some that might break dolphin, but main codes work. I still recommend more testing of this fix. I will now work on the next fix. =). Also some code cleanup.
