+Execute renames:
+<code>
+  find /mnt/DOCS1/ROMs/Library/roms -type f \( -name "*, A *" -o -name "*, An *" \) | sort | while IFS= read -r filepath; do
+      dir=$(dirname "$filepath")
+      filename=$(basename "$filepath")

+          mv -- "$filepath" "$dir/$newname"
+          echo "Renamed: '$filename' -> '$newname'"
+      fi
+  done
+</code>
+Key sed pattern:
+  - s/^\(.*\), \(An\{0,1\}\) \(.*\)$/\2 \1 \3/ — \(An\{0,1\}\) matches either A or An, captures it as \2, then reconstructs as \2 \1 \3
