The data read are stored in the second memory block. The first memory block is filled with hashes, in an unknown manner.
Reads seem to be sector-aligned (one sector = 0x1000 bytes when reading from the cart, not sure if that is true everywhere). The first memory block seems to be filled with one hash per sector read.
