17. This byte in the snapshot represents the index of the currently selected PSG register. For CPCEMU compatibility, this byte should be in the range 0-15.
18. the first 64k memory dump can have size 0 in version 3 and in this case all RAM is always described in additional blocks (MEM0-MEM8). If a memory dump has a non-zero size, then it is uncompressed and describes the base 64k of main 64KB ram. The immediately followed by the second 64k 64KB ram (if present) is the additional (this ram in is inside 128KB machines or machines with 64KB from a Dk'Tronics/Dobbertin/Amstrad compatible RAM expansion or the internal ram of the CPC6128/CPC6128+. The memory dump is not dependant on the current RAM configuration. Note that CPCEMU can only write a 64K or 128K snapshot.
