With this program you can change everything in NAND but MSID
returns after reboot card.Before reading through DMDE i removed attr0.bin from the card file
.Therefore, to be able to replace the MSID, I suggest making interface for the popular AVR controller.Then the possibility of substitution would be possible on all cards, even in the new. I'm working on it.
Was eliminated the need to buy an expensive NAND programator, and the need for technically complex soldering/desoldering.MSID swapping would take place outside the card.
I will spoof a MSID. Input and output would be equal outside &H1B0 (where the MSID is).This would depend on the software written for this AVR controller.
Actually it's not about replacing MSID in NAND but beyond.Would match all the cards then.
Card communicates with the PSP via a parallel transfer only?
