Ok Dragonic, i was in ur place a while ago, and couldnt get ANYONE to tell me how to do this, until Ben was nice enough to tell me.
Inside the Rogue Spear > Rogue Spear Data > User folder there is a file called boundkey txt.
u have to open this file, and edit the messages there, and use sound file names from the Rogue Spear > Rogue Spear Data > Sound > English folder for the sounds
Once you do this i suggest that u make a backup copy of it and keep it elsewhere on ur hd b/c if u open the mp bound messages in the rs settings, the sounds that go with the messages that are not standard (ie the TEWOGGA sound) are erased
If u have any more questions, post them in this thread and ill try to answer them.
