Hi I'm reading here and there some information about HANS. If i'm not mistaken, it can be used to launch custom game of a retail game, using extra files places on the SD. Does that impact the saves already present in the game or does it use a safe place (for saving) in the SD card when using the game with HANS ? Also, i'm a little bit confusing when i read some info about HANS and hack roms. Hack roms do not need HANS to be used right ?
