the only thing I can think of if that it is that the spelling of your stage in the def is different than how its spelled in the stages folder. can you use the stage otherwise?
here is what I do answer and say hello if it is indeed a telemarketer just hangup and continue what i was doing so it goes something like this me:hello? telemarketer:hi I'd like to.. *hangs up phone
well the best thing to do would be to read whats in the docs folder and if you get stuck while creating you can always try asking at http://randomselect.com or http://mugenguild.com even here and I'll try my best to answer your questions
all you realy need to do is add the sound in the snd file using the sound editor in fighter factory make sure it has a unique group number and use the playsnd sctrl in the state where you want the sound to be played
