Format:SNA snapshot file format

675 bytes added, 9 March
== V3 Chunks ==
=== CPC+ Chunk (Plus only) ===
Chunk name: "CPC+"
|}
=== Memory block chunks (CPC/Plus/KC Compact/Aleste) ===
There may be 1 or more of these memory blocks.
i.e. <control byte>, <count>, <byte>
Examples(Uncompressed = Compressed):* 11 22 33 = 11 22 33* E5 03 11 = 11 11 11* E5 00 = E5
Uncompressed = Compressed11 22 33 = 11 22 33= Breakpoint chunk (Winape emulator specific) ===E5 03 11 Breakpoint chunk has the name "BRKS". The chunk contains 1 or more breakpoints. Each breakpoint has the form: 2 byte address1 byte code (0= 11 11 11base 64K RAM, 1 = extended RAM)2 bytes condition E5 00 = E5== Inserted disc images (Winape emulator specific) === There are two chunks. 'DSCA' and 'DSCB'.DSCA is for drive A and DSCB is for drive B. The chunk contains a string which is the path to the disk image inserted into that drive.
== Memory ==
Uncompressed memory described by the snapshot allows sizes of:
* 64K (base 64K only),
* 128K (base 64K + 64K dk'tronics compatible RAM expansion using ram selections C4-C7),
* The snapshot format doesn't support additional hardware. A basic CPC464, CPC664, CPC6128 system is assumed.
* The snapshot format doesn't support KC Compact or Aleste hardware.
* The snapshot doesn't have knowledge of which ROMs are in use. This means it doesn't know which OS, BASIC or AMSDOS ROM, and nothing about expansion roms. On Plus range, it doesn't know which Cartridge is loaded.It The format generally assumes a base CPC6128/6128Plus system with ram expanded no attached hardware except for up to 512Kof dk'tronics compatible RAM.
