what the heck am i missing?

ok, guys here is the rundown, I am in the process of modding my sons old ps2(fat),This is my goal, I want to load all my game to the hd and never have to use a disc again. I will be upgrading soon to a PS3!! I already have the official sony adapter, I already formated the seagate 80 gig, Hard Drive with XP (and yes I did check the compatibility list so I am good there.)I also managed to load spiderman 3 on the hd before i installed it back in the PS2 via winhip. I picked an old copy of swap magic version 3.6 (it's a bit scuffed up) and I downloaded HD advance and burned it to a disc.

Now here is my problem, swap magic loaded up about for maybe five time when I first got it, now it does nothing. So my question is how do I get to spiderman?? do I buy another fresh copy of Swap magic or do try and make a bootable usb ? I am kinda frustrated guys...sorry for venting, any help would be great!!!!

 

anyone?
