UA6527P is the name of IC that acts like a CPU in many famiclones.
I bought also UA6527 which is very rare. I recorded music from two games on those chips (on the same game console, with 26.601712 MHz crystal). First game is Duck Tales II, the second one is Doki Doki Yuuenchi. The music is very different on those chips. Can someone give reason? Is it because of diffrent duty cycles?
