One of the advantages for me (using HDLoader) is that I can put about 95% of my game collection (I own over 50 games) into myHDD. Now I can carry my entire collection (almost entire) anywhere. Pardon my french, but THAT ****ING RULES!!!
All you gotta do is go out and buy a huge Maxtor HDD (stay under 300gb just to be safe, all Maxtor HDDs work). I bought a 200gb Maxtor HDD for $129 with a $50 mail-in rebate, making it $80+tax! I garauntee you can fit at least 50 games on it! I can't even begin to tell you all the great stuff you can do with the memorycard exploit once you're packing a big ass hard drive!
Dip-Set all day, everyday!!
