As you all know Sony released the HDD along Final Fantasy XI. The only problem with the peripheral is that no one supported the darn thing. And I'll be darned if im going to spend 10 hours of my life fighting rabbits and dogs just go up one level and on top of that pay $10.95 a month!!!! So what can i use the HDD for?? Easy, HD Advance. HD Advance is a software for PS2 that lets you directly copy games onto the HDD and play them without the disc. Its amazing, you only have to keep the HD Advance disc in, turn on the PS2 and select the game from the list. The only catch is that you have to have a modchip in your PS2. I modded mines years ago simply because there a ton of Gundam games that never make it out here.
