Oui:
* You can convert SPC files to WAV using Super Jukebox and WAV, MP3, OGG, WMA etc. using Winamp.
* In case you are sick of those short 8.3 style file names of all SPC files in this archive you can use SPC Renamer for renaming all files into your prefered naming scheme in one rush. Under KDE you can do the same with KRename after you have installed the above mentioned kfile_spc.
* You can also export SPC files as MIDI files, export its containing samples and even replace existing samples with your own recordings using SPC Tool for DOS.
