i had hd loader and i backed it up to my hard drive then i lost my original before i ever used it. now i have the original swap magic dvd and a cd image of hd loader. i never got the chance to set up my ps2 and use hd loader. can i set up the network adaptor and my hard drive, then use swap magic and swap to my backed up hd loader and then use that as i would normal hd loader? or will i need to get another hd loader disc?
