magic 3.1 works by making the dvd drive spinner spin faster than usual. Thus tricking the ps2 into playing burned games. Say one day u wonder why I cant play games anymore. Maybe it's cuz you got a mod chip. So one day notice the dvd drive is spinning too fast, making it too fast from the PS2 playing games. So you take mod chip thinking this will solve my problem. This doesnt work because you already changed your system from its default setting. Unless you know how to slow it down, I guess you got a problem.
