+Changes in the current code since fc-host-tools-r16:
+
+* A special reverse engineering command named tfc139-audio-dump has been added
+  to fc-loadtool; this hack command does anything interesting only when
+  fc-loadtool has been entered through tfc139 (breaking into a running Compal
+  firmware), in which case it will dump some audio settings (DSP API words and
+  Iota ABB registers) which should persist from the official firmware that has
+  been broken into.

 Changes from fc-host-tools-r15 to fc-host-tools-r16:
 
 * tiaud-compile and tiaud-decomp now support two versions of the audio mode
