OK. I finally got my hands on a PS2 with a Matrix Infinity installed. How do I set it up so that I can hold R1 to boot HD Advance off of the memory card with no disc in the tray? I keep hearing about hdloader.elf and other .elf files, but where do you find them? This is the first time I have ever tried this, so bear with me. Are there any walkthroughs specifically for users of the Matrix Infinity?
