Ok good news i think i searched for that hex value and i found it, i also noticed that its just before a CD001 string (or whatever its called) so for this value i just change the first 4 bytes and then i should be set?
As for the other .bins i remember reading somewhere that they only required hacking so internet access works correctly, but dont quote me on that.
So now if i follow what i just did on all the .bins i should have one working selfboot game
however youre going to hate me now

i noticed you mentioned this doesnt work for CDDA games, could you put what i need to do for games with CDDA, cause i got a couple of them to do.
Ive already selfbooted a few, its just incase i get this same problem with a CDDA game. (also i notice that a few CDDA games come without the music, so if i got one of these should i treat them as CDDA or just normal games?)
