Currently all i want to do is have a successful and non-damaging way to load custom guitar hero's on my PS2. should i: A. get a ps2 and a modchip a. do i need anything besides the modchip/wire? b. will this damage my system after installed correctly?(laser damage) B. get swap magic discs or some kind of boot disc a. will this let me boot ps2 backups? b. do i need something else? (solderless modchip?) thank you. if you suggest one or the other could you please link me to the correct location to find what i need. thank you thanks chris.
