Added odd cycle rounding and adjusted reset phase & time. Replaced the APU frame divider singular "half counter" with a table. Added Memory View window. Fixed sound-off speed issues by internally rendering silent samples at 4998 Hz. MMC5 PCM now disabled at init. (ROM must clear $5010 bit #6 and #0.) Fixed a mapper sound bug and some shell bugs/issues. Added ability to adjust the DC filter (or turn it off). Higher quality sound playback of high sample rates on most Macs.
