+Nach's insane subtitle library for movies files :)
+
+The filename would be gamename.sub in the same directory the ZMV would be in.
+If you're playing gamename.zm1, then the sub file will be gamename.su1 etc...
+
+Format of the sub file:
+Start Frame:Frame Duration:Message
+
+Example:
+1:180:Hi how are you?
+300:180:Isn't this cool?
+700:180:This is great :)
+2500:375:Kill 'em!
+3500:20:Did you see this?
