added some very limited support for Mac Loom (text is now properly centered around x:160 instead of x:0); added (commented out) copyprot bypass (but since I am not sure if there was ever a Mac Loom w/o codes, am not sure if this ever should be enabled); added comment regarding the Mac Loom sound format
