@@ -21,6 +21,7 @@ Fixed inverted switches for ffv101
 Fixed regression in DCS Audio decoding
 Also fixed one subtle DCS emulation bug that leads to slight buzzing/crackling on some samples though (mainly audible when using good speakers or headphones or if the internal volume is cranked up very high)
  one of the longest standing bugs in the history of PinMAME!
+Due to the above, remove DCS low pass filtering (introduced in 2.8) again and prefer 1:1 DCS output quality
