I got USB Advance to work on my PS2 but I used my friend's Flash Drive so I'm gonna need to click+drag the .elf file into my own Flash Drive when I get back home... but the question is, does my flash drive need to be a certain size for my PS2 to read it? I own the earliest (launch) PS2 model. Can it play downloaded .iso files or will it only work by extracting .iso files from PS2 games? Do I need to reformat my USB HD for it to work on USB Advance? Right now it's in NTFS.
