 ===== RENAME 'The' ROMS =====
+. Dry-run preview (generates rename list without executing):
 <code>

-           echo "'$filename'"
+          newname=$(echo "$filename" | sed 's/\(+ \)\(.*\), The \(.*\)/\1The \2 \3/')

+. Execute renames:
+<code>
+  find /mnt/DOCS1/ROMs/Library/roms -type f -name "*, The*" | sort -u | while IFS= read -r filepath; do
+      dir=$(dirname "$filepath")
+      filename=$(basename "$filepath")
+      # Special case: combo pack where ", The" belongs to a subtitle within the combo
+      if echo "$filename" | grep -qP '^\w.*\+.*[,] The '; then
+          newname=$(echo "$filename" | sed 's/\(+ \)\(.*\), The \(.*\)/\1The \2 \3/')
+      else

+      fi
+      if [ "$filename" != "$newname" ]; then
+          mv -- "$filepath" "$dir/$newname"
+          echo "Renamed: $filename"
+      fi
+  done
+</code>
+Key sed patterns:
+  - Standard: s/^\(.*\), The \(.*\)$/The \1 \2/ — captures everything before , The  as \1 and everything after as \2, then prepends The
+  - Combo pack: s/\(+ \)\(.*\), The \(.*\)/\1The \2 \3/ — moves The to before the subtitle within a +-delimited combo title
+===== RENAME 'A', 'An' ROMS =====
+Dry-run preview:
+<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")
+      newname=$(echo "$filename" | sed 's/^\(.*\), \(An\{0,1\}\) \(.*\)$/\2 \1 \3/')
+      echo "'$filename'"
+      echo "  -> '$newname'"
+  done
+</code>
+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")
+      newname=$(echo "$filename" | sed 's/^\(.*\), \(An\{0,1\}\) \(.*\)$/\2 \1 \3/')
+      if [ "$filename" != "$newname" ]; then
+          mv -- "$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
