This map format has come across Artwork's desk but no information is known about what software/equipment produces nor do we have any specification on the format.

The MAP Section

This section appears straightforward. For each row there is a single line of bin codes. Each row begins with MAPNNN where NNN is the row number starting at 001: MAP001, MAP002 ...

The codes appear to be two character ASCII as we have seen in the file: 00, 01, 99, XX. The XX rules out hexadecimal. There are no spaces or other delimiters between the two character bin codes. We do not know whether special characters are allowed for bin codes such as __ or @@ as one would find in SINF.
