Why do older video games and movies worst audio then newer ones ?

That could be based on several different factors how old is the video game are you playing first of all because most video games now use a Blu-ray disc this holds about six times the information that a regular double CD holds a regular CD holtz about half of that which is about 600 to 700 megabytes then you go back to a Nintendo 64 the reason it was called a 64 is because it only ran on 64 megabytes an old-school Nintendo not the original but the older ones ran on 32 megabytes and the ones before that we're only 8 megabytesif you're playing like the original Zelda you're playing on a 32GB systemnow when you go to the modern Zelda it's being played on a Blu-ray disc which is approximately a thousand times more information this allows for full video and full audio in the video game.
