ok so this is the problem im currently experiencing.

I know its something to do with the soundblaster because i had this problem in regular dos back when i was playing wolf3d for pc (sound part only)

the rectangle at the bottom of the screen i can only imagine is being caused due to some sort of resolution error

It looks fine on the screen, with no lag, and i can kill the bad guys open the doors etc. thats about it, if you think you know why this is being caused some insight would be handy. i still to this day have no idea why the sound randomly cuts out after X amount of soundblaster sounds are played, thanks!
