About selfbooting Perpetual Blue

[Megalexxx]

I think my first idea was right : problem comes from these SFD movies.

I managed to boot the game, but instead of Title.sfd, I've got a black screen.
BUT, this time, if I push start or A button, menu loads fine.

What I did : I changed the "6C 24 06 8C" by a value much lower. I think it's some kind of LBA check, but replacing it by the file's LBA doesn't change anything. I also tried to substract only 45000, but it does the same thing.

Any idea ?


Edit : this value is the address of the SFD to load. If it's changed, the SFD player can't load any file, show a black screen, but at least, doesn't freeze...
