Sounds very neat!

Isn't possible to use PackAppInfoBlock() to create/modify
an AppInfo block?

Oh yes, oh yes, oh yes :-)

From what I've been able to deduce:

Bytes 16-32 are the second half of the field "Name" . For a
pilot-db file, this should contain the name of the database, the
extra bytes being zeroed out.

All the pilot-db databases I've ever handled have an AppInfo offset
of 88 which means that the pdb header is 136 bytes long. I have no idea
what bytes 182 and 183 contain.
