Ps2rd is a handy tool to do comparison based scans while playing games. Pcsx2 is a handy tool to play PS2 games on your computer so you can use another PC tool to scan as you go. Cheat devices are handy for guessing and checking. Values at addresses come as bits, integers, decimals, or addresses. What game and what are you looking for?
