Soundcraft SHow?

Format

Actual format is XML.

Unfortunately it's full of blobs but don't worry!

XML Sections

Device

NODE

Show

• name: (str) This is a cleartext attribute with the show name! Yay :)

MHxDFile

• name: (str) Looks like a path and filename.
  • "._ $SHOWS\Show_0\filename.ext"
• checksum: (int) Undetermined checksum. (Yet!)
  • TODO: determine checksum type.
• datalength: (int) Size of the uncompressed data blob in bytes.
• content: blob

Blobs

All blobs seem to start with the same header: 'eJz'.

Looks like some kind of data encoding or compression.

Base64? Most likely. The resulting files looks encoded or compressed though…

78 9C header. Doesn't that look like zlib? \o/

Recipes

Decode & Extract

< "XML MHxDFile entity content in a file" base64 -d | zlib-flate -uncompress > file

Compress & Encode

< file zlib-flate -compress | base64 -w0 > "XML MHxDFile entity content in a file"

*.dat files

Looks like memory dumps. 180kB. Very similar content.

Start with "Snapshot" header.

SS_xxxxx.dat

Purpose unknown. Certainly the current state since it's restored on show loading.

SS_x.dat

x = snaphotId from ShowHdr.xml

Looks like the cues. The number of sections match the number of cues of the show.
