Hello,

I have a strange problem with my SCPH-1002 PAL.
The console was capkit(ed) as well as the power supply.
Equipped with an MM3.
My optical unit is really good with an RF/eye pattern at 0.6V on my burned backups (1.2V PP).
First strange thing: I have a worse signal on my original CDs which are, however, clean (0,45V - 0,9 PP).
My CD-Rs are "classics" PhtaloCyanine FTI burned on my Plex Premium in 4X.
The second annoying thing is that I have a few rare games that don't work either in original or copied versions.
Like, Gran Turismo, Parasite eve 2 ...
Same thing with my chip disabled.

Gran Turismo block after the "advert" screen (screen after SCEE logo and white full screen text "Sony computer Europe").
if I remember correctly, there must be a video right after this screen and the drive must be in double speed ?!
Same problem with GT2.
I have a lot of games that work well otherwise.

Can it be a Driver/buffer dead chip ?

Thank for your help and happy new year ^_^

A laser reads the disc, starting at a standard location. By reading a series of these pits and lands, it can determine the name of the game and everything else that goes with it, like the graphics and sound. It reads all the data and shoves it into RAM, where it can actually do something with it, like play the game or run the process to copy the game to the console’s internal secondary storage (hard disk or SSD) pikashow
