Hello,
I've encountered a bug with WACUP #6800 (and earlier) involving the tags for SPC files. It seems that the ATF setting overwrites the ID666 tags in both the playlist and the File Info section. Disabling it corrects the problem with SPC files in playlists, but the File Info window is still incorrect, and obviously it isn't ideal to disable ATF universally for a problem with one file format.
