- 0.146: Couriersud improved sound emulation for POKEY chip. Changed audio emulation to emulate borrow 3 clock delay and proper channel reset. New frequency only becomes effective after the counter hits 0. Emulation also treats counters as 8 bit counters which are linked now instead of monolytic 16 bit counters. Fixed high pass filters for POKEY. Added POKEYN device based on modern device. Fixed random lfsr generation. Consolidated polynom code. Removed legacy left overs from pokey code. Added a internal pokey_channel class. Convert all remaining drivers to use the modern pokey device.
