Atari 2600, 5200, and 7800 themes worked fine for me on HyperHq v2.0.54 . I installed Retroarch through HyperHQ. Try deleting your Hyperspin and HyperHQ files inside your user AppData folders.
The Emumovies access issue was a me problem. It appears that Nord sees Emumovies as a threat but doesn't like to notify that it is blocking... Issue is resolved. Leaving this up in case anyone was actually watching this thread.
