Palm Desktop to native memopad PDB file (without device)

Hello. Is there any program that would convert Palm memos from the
desktop program to the native memopad PDB file and back, in Windows
(that is, without a hotsync to a Palm device)? The purpose is to
update the memopad PDB file I copied to my WIndows Mobile device with
Styletap. Doing this is not true hotsync, but would be an acceptable
alternative since Styletap does not hotsync.

Normal hotsync apparently does not even store the native Palm memopad
file in windows in the backup directory, using instead the special
desktop files.
