In 2012 I made a loader plugin for Black Chocobo save editor so users can edit FF7 saves
directly from MemcardRex.
It simply takes a single FF7 save, stores it to temp directory, sends it to Black Chocobo and waits for the application to close so it can put the save back to MemcardRex.
I named the temp file "FF7SaveData" and that worked when I tested the plugin.
However in the mean time Black Chocobo was updated and now it expects a decently named file to
detect it as a single save (eg. "BASCUS-94163FF7-S01").
Because of that BCLoader 0.1 is not usable with Black Chocobo any more and
the save is not detected as Final Fantasy VII save.
This has escaped me as I don't use Black Chocobo.
Fortunately user Jack Barnard pointed out the problem with the plugin.
So I fixed the problem and got the plugin working once again.
So, here it is. Grab the updated plugin and replace old "BCLoader.dll" in
plugins directory with the new one.
