Hence you're using your laser and it's having trouble with DVD backups which is why I came to the conclusion that the DVD coil is weak. Burned discs (expecially DVD are harder on the coils and will show if the coil is weak. Which brings me to backup dvd will not load
So first i bought a copy of Swap magic 3.8 coder and i got the dvd and cd version. Both of them start up fine except when i try to load a backup. The first game i tried was mgs 3 substance that i know works because i tried it before on a different modded ps2.
So i slide carded it, did the procedure and what not and it gave me the black Screen of death. However the game did start up once, so i restarted the system to see if it would work if i tried again...it didn't work. So i tried final fantasy 10 and 10-2 both with the same result
So then i tried the cd version of swap magic and tried the refreshing toc method. every time i tried loading the backup, i would be kicked out to the browser. then i tried using a cd backup...this worked! I've learned that the cd backups run no problem.
