[fuse-emulator-devel] Spectranet snapshot blocks

[Alistair <ali...@zx...>]

I've been trying to make sense of the .szx files Fuse creates with 
spectranet enabled, which didn't match the description Phil had added to 
the sinclair wiki

https://sinclair.wiki.zxnet.co.uk/wiki/ZX-State_format#ZXSTSPECTRANETFLASHPAGE

I've made an edit to change wFlags to chFlags and add two DWORDs but I 
can't fathom what the first is supposed to be. When the snapshot is 
converted to uncompressed with snapconv it comes out holding a 
big-endian copy of the data size, but on compressed snapshots I can't 
make head or tails of it.

It's apparently the value of flash_buffer->bytes_used when the snef 
chunk is being written, but I've seen values from 1 to petabytes.
