In the third copypaste, the value that indicates the offset points to the 'exception' hash inside the '''hash_table''' (bytes from 0xEFE68C up to 0xEFE6A0 are copypasted to 0xEC0108 up to 0xEC011C), but instead of copying the 'exception' hash it copypastes the default hash value | In the third copypaste, the value that indicates the offset points to the 'exception' hash inside the '''hash_table''' (bytes from 0xEFE68C up to 0xEFE6A0 are copypasted to 0xEC0108 up to 0xEC011C), but instead of copying the 'exception' hash it copypastes the default hash value | ||
At this point the creation process is near completed, the only thing left is to fill the 0x10 bytes at the beginning in the first vtrm block (at 0xEC0000), this small area is going to work as the entry point when reading the whole vtrm, and this is when is written the 'magic_scei' that is unique (is the only value from this blocks in common between NAND and NOR), the other thing that indicates this area (with the value 0xA8) is the | At this point the creation process is near completed, the only thing left is to fill the 0x10 bytes at the beginning in the first vtrm block (at 0xEC0000), this small area is going to work as the entry point when reading the whole vtrm, and this is when is written the 'magic_scei' that is unique (is the only value from this blocks in common between NAND and NOR), the other thing that indicates this area (with the value 0xA8) is the lenght of the areas that has been copypasted below (but only the sum of the first two copypastes, for some reason the third copypaste is not included in this sum, also the position where the third copypaste happens is a bit weird i dont get why that position, is because the 0x40 gap but that gap makes no sense, the point is the gap is there and is related with the reason why the third copypaste to not be included in this sum) | ||
