The sound code is were your seeing the slow down. It is the weakest part of the code IMHO. I dont know that added hardware will help the current solution. Optimising the program for the game you wish to play might help as you
will be removing much code that is not needed.
input and code enhancement is always appreciated. Credit will be assigned for any code used.
