[buffy_the_slaye]

Hello, i need big time help... i have a version6 pal ps2, and i have a flip-top cover and swap magic DVD v2.0(+ CD v3.0) europe build disc.
so i have downloaded Naruto: narumett hero, swat, XIII, suikoden3 and Forbidden Siren. i have burned al of them using nero, and later i used alchohol 120%.... i burned them on dvd-r and +r... and for some reason only naruto and XIII worked right away and the rest didn't... now i found software called CDLoader (for the ps2V1-6 and V7) and they should have solved my problems with swat and suikoden3.... but when i boot swapCD->CDLoader->SwapDVD and then insert swat or suikoden3, it says: "WRONG MEDIA". i have visited many forrums and sites and they als say that is should work.... but it doesn't.
CAN ANYBODY PLEASE HELP ME!!!!!!
THNX

I don't think the PS2 will read DVD+R disks. I am assuming the games that don't work are DVD+R. Am I right?
