+# 20180730 bkw:
+# - BUILD=2.
+# - add libretro/RetroArch, thanks to orbea.
+# - add --without-portaudio to configure args. snes9x runs about
+#   1 frame/sec if I start it up with the sound driver set to portaudio,
+#   and I've gotten a report of it blasting high-volume white noise
+#   thru the speakers if you switch to portaudio while a ROM is already
+#   running. I can't see any reason to use it in favor of pulse, alsa,
+#   oss, or sdl audio.
+# - don't extract windows, mac, old-school unix stuff from tarball.
+#   uses 50% less $TMP space.

 # 20180623 bkw: update for 1.56.2.
 # 20180611 bkw:
 # - update for 1.56.1.
