MBM File
MBM files are basically Sketch files with a few things stripped.
MBM files start with a Header Section which starts with the following codes:
Offset Size Data Description
0000 ID 37 00 00 10 UID1: Header Section layout
0004 ID 42 00 00 10 UID2: File kind
0008 ID 00 00 00 00 UID3: Application ID
000C L 39 64 39 47 UID4: Checksum of UID1, UID2 and UID3
0010
The Section Table Section only contains a single offset address, unmarked by an identifier. This offset points to the Paint Data Section
