Notes and Comments

• The first few bytes of the filenames are encrypted, the last few bytes are not encrypted.
• Also, the files are compressed using some kind of flag field amongst the data that tells how to decompress them. The flag fields are all 1 byte long? The compression *may* be similar to that used by Maxis in the DBPF-based archives?
