enabled using encrypted action replay codes, just put them in the gameini file, and they are decrypted when read. Note: the first line of a "real" AR code is a verification code, which dolphin's simulator currently missreads. I'm unsure whether to bypass the code by skipping it in ARDecrypt.cpp line 489, or think of some actual solution :p
