Summary	06142: mcontest: missing sound/music
Description	Music and many sound effects are missing, it worked long ago but I don't know when it broke since I haven't played these games in a while. I have an old 0.148u1 and it's working there, but there are a lot of versions in between. Unfortunately reproducibility seems to have to do with when you coin up and hit start.
Steps To Reproduce	* Launch mcontest driver * Insert a coin and start game * Missing sounds as dialogue text is displayed * Missing sounds during item roulette animation

No.12406 Tafoid Administrator Feb 24, 2016, 17:26	I can confirm that is is indeed a random thing. Even with 0.148u1, I was able to get the lack of music/sound as you mentioned when crediting at a certain time.
