hi guys i got a v9 ps2 which boots swap magic perfectlly the p[roblem is my friend's slim ps2 wont boot it. Both mine and his version boots on mine and the cd loader boots on his ps2 but the dvd doesnt. I thought maybe it could be the laser is weak but it boots his non-backup ps2 dvd games perfectly. Anyone can suggest something? Otherwise he paid 20 bucks for nothing
