If you currently have sm-ssc, you may be tempted to test moonlight in it.
Before you do, uncomment #FallbackTheme=_portKit-sm4 in the metrics.ini file.
That will load the portKit needed for moonlight to operate without errors.

The theme won't look exactly the same in sm-ssc as it does in SM4, and a lot of
that has to do with sm-ssc/the portKit. (moonlight is the main test case for
portKit-sm4, for those wondering.)
