Need some help understanding things like HD Loader
I read the pinned tutorial for most part but I didn't see anywhere in it, explain what exactly HD Loader is? I am compeltely new to this and also completely confused. I have come to realization that I have a v5/v6 ps2 and also I have the HD that I bought with final fantasy XI and the online adapter. Can someone explain to me more clearly what HD Loader is and just a simple list of things I need to softmod my ps2?
O and if it helps any I have softmodded a few xbox's.
