EPOC MBM (also known as MBM, Psion Series 5 bitmap, or Symbian Multibitmap) is a raster image file format associated with Psion's EPOC operating system, and its successor, Symbian (most notably used by Nokia phones). An MBM file can contain multiple images.
Images may be grayscale, palette color using a predefined palette, or (less commonly) direct RGB color. They may be uncompressed, or RLE-compressed.

Identification
MBM files begin with (hex) bytes 37 00 00 10 42 00 00 10.
There is an "exported MBM" format, which begins with 37 00 00 10 8a 00 00 10. Aside from that, it seems to be identical to the main MBM format.
