error's with mortal kombat enchanted

[GunS29]

the game starts but certain settings are unstable like for example vertex cache when enabling it the game goes to the mem check then the screen goes black with popping sounds when disabling it the game check the mem stick and then again the screen goes black with popping sounds but i press the start button 3 times the game so to the main screen but never reaches the character select screen all in all the prebuilds move alot faster.
the screen turn black with popping sounds when implementing the media engine im not sure if its the media engine or vertex it sems to me both need to be fix bud they r doing a hell of a job with this emu this is the best i have so for and goes to shoe anything possable and yes i am talking about mortal kombat unchained
