If you download the game image and view it from any hex editor, the first 16 bytes of the file are 1A C8 91 1A 88 CA 10 E2 60 C0 24 EC 16 B8 5A 34
However when viewing from the screen dump [Disassembly tab] via the web page, the first 16 are 48 BA 86 43 A2 27 9A A5 03 29 20 F0 6D E6 41 D0.
The sane bytes are found at offset 0x1400 when viewed via hex editor. So the first 5120 bytes are missing when viewed from the hex dump [or Disassembly] tab.
