Format details

The first 10 bytes of the file are "a standard AMOS file header, as generated by a PHDR statement." The header ff ff 00 01 64 00 00 00 03 00 has been observed, but is probably not the only possibility, and is probably not unique to BMP format.

Following that is a 70-byte bitmap header, of which the last 60 bytes are used for a comment field.
