ATARI POKEY 8-bit Computer Sound on PIC32
I successfully compiled the ASAP (Another Slight Atari Player) library  for a PIC32MX795F512H. ASAP emulates a 6502 CPU and the famous POKEY sound chip  used for example in the ATARI 400/800 and XL/XE 8-bit computers. To say it with Wikipedia’s words: POKEY’s sound is distinctive
About 60 tunes (worth about 2.5 hours of music) taken from ASMA (Atari SAP Music Archive)  are included and stored in the PICs flash memory. D0 is the left and D1 the right PWM channel.
