   −
The data read are stored in the second memory block. The first memory block is filled with hashes, in an unknown manner.
+
The data read are stored in the read buffer. For each 0x1000-byte block read, a SHA256 hash of the block is stored in the hashtable.
   −
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.
+
It is unknown how hashing behaves if the read offset/size are not aligned to a 0x1000-byte boundary.
