Hello people, I'm new to this playstation 2 games. I might sound like and idiot here. I have a question if anybody can help me. I would greatly appreciate that. I have a PS2 that I just purchased 2 days ago model# SCPH-77001 (Slim) and I would like to play with my back up games. I made my research and I ran into this PS2 HDXtreme sofware, can anybody tell me how to install this before I buy the software? Is it you need an external hard drive connected to the USB in PS2 and load the software from the PS2? Please give me a step-by-step instruction. Thanks in advance!
