Ive had my N64 since it came out in 1996 and ive always taken very good care of my games. Ive noticed recently that some games with certain sounds have a glitched static sound to them everytime I play the game. And its not just one game,its alot of games and I have no idea why this is happening. The only hypothesis i have is the gameshark because my friends Goldeneye game makes the same glitched sounds only much worse,and thats a game that he hacked alot back in the day. Ive tried all my games in a different system and still the same result,glitched sounds in Rush 2's intro music,if I have enough explosions on the screen in Perfect Dark,glitched sounds..its yea,i would like to know the cause and maybe how to fix it somehow.
