PMGI chunks 001C: DWORD Chunk number of root index chunk, -1 if there is none
(though at least one file has 0 despite there being no index chunk, probably
a bug) 0020: DWORD Chunk number of first PMGL (listing) chunk 0024: DWORD

directory chunk 0008: Directory index entries (to quickref/free area) The
quickref area in an PMGI is the same as in an PMGL The format of a directory
index entry is as follows: BYTE: length of name BYTEs: name (UTF-8 encoded)
