this seems to happen on neogeo section as far as i know.. i changed from svcsplus to ss2 n the noise glitch started happening.. i had the memory card inserted(neo geo emulated on fbaxxx) took it out n then it started the glitch edit:ok this happenes even with out the memorycard inserted...again, i went from svcsplus to ss2 n it happenes again, if you change from ss2 to another neo game, sound problem its still there.. only happened on pro version. tryed regular fbaxxx n i cant reproduce it.. edit2: ok after some more testing, it seems that svssplus its the cause of this,, i tryed different games n no luck, i can only reproduce this glitch when i launch svcsplus then quit n change to another neogame
