The file consists of two parts, the administrative data in ASCII and the binary image data. It is possible to put both in one file, but we prefer to separate the data into two files. The administrative data in a file with extension ‘.h33’ and the binary data in a file with extension ‘.i33’.

This is a wonderful feature! Because of the separate header in ASCII you could write your own header for any raw image data you may have. I regularly use InterFile for turning unsupported formats into a supported format. Try to extract the raw image data from the unknown format and add an appropriate header with all information you know about.
