File type specification:
The ZX82 file extension is related to Speculator and used for its emulator format. Amiga Speculator has its own file format which called ZX82 format because it contains a file identifier in the first four bytes consisting of the ASCII characters "ZX82". The format has a 12 byte header which contains the normal Spectrum type file information like length, type, start etc. as well as a compression flag which is set if the file is byte run compressed. Snapshot files have a further 32 bytes of register values and border colour information. Listed below are the offset definitions taken from the Speculator source code in case you need to write a conversion utility. All registers and other values are in Motorola format (High, Low).
