Before you senior/major members get pissed-off about this. Trust me, I have taken this in consideration as I read most of forums on how to write and read .iso files and many others. The problem is; I have 100 count of maxwell dvd-rs and magic swap 3.6 cd-rom and dvd. And the new silver slim PS2 with magicswap keys inside (I put them there, obviously). I followed most of post-er's steps on how to back-up a PS2 game. However, after 17 burnt DVD-Rs, nothing seem to be working. My screen still says, "Not a valid PS2 disc." after putting the magicswap dvd/cd inside the PS2. (I quickly took 5 seconds to swap the MagicSwap dvd/cd to burnt dvd-r) I also have tried thrice with memorex DVD+R. I used both Nero and DVD Decrypter. So... Help? I'm pretty new at backing-up PS2 games and pirating PS2 games. PS: I am also worried about money issues because I'm a poor college student, see why I'm asking for you guys' help because I don't want to put any dvd-/+rs to waste. x_x; $30-$40 is expensive to me.
