@DJ-VAN: So you believed that the settings were stored in the DLL itself, rather than in an INI file? ???
Even though you appear to know something about what CRCs are? ???
@Messatsu: Damnit, don't force me to use "@" signs in my post by replying too quickly!
Edit: Whoops, little correction. Some plug-ins use "plugin.ini", some use "[plug-in's name].ini", and some (including Nullsoft's in_mp3.dll) use "[calling program's name].ini". Briefly forgot about that detail, sorry.
Still quite busy.
(Yes, I intend to deal with that stuff eventually, but kinda can't just yet, sorry. :/ )
