Disable lowpass again, remembered the filter is explicit for spdif output (where it matters). Make spdif component explicitly have a port for left/right. Get all versions building again (some needed old dac for space reasons). Change default volume for adc and sio mixing for v4.5 (SHOULD not need the filtering there, testing now).
Added two new components: sync reset and 2nd order dither.
Added audio signal detector
Add some unused stuff to the qsf
Added wide delay line for register delays
Moved pokey to own folder
Use schmit trigger for SID and BCLK inputs
