@@ -30,3 +30,12 @@ Optional dependency: rtmidi (autodetected). If rtmidi is installed
at build time, 86box will be built with support for it. If you have
rtmidi installed but want to build without it, export RTMIDI=no in the
environment. MIDI will still work without rtmidi.

+Optional dependency: gamemode. This is a runtime dependency, so it can
+be installed at any time without having to rebuild 86box.
+
+Note: Starting with version 5.0, 86box requires SSE2 extensions to run
+on 32-bit x86. Unless your CPU is over 20 years old, this shouldn't
+cause a problem. It's still possible to *build* 86box on a system
+that lacks SSE2, but not *run* it (you could install the package on a
+different machine that has SSE2 and it would work).
