How to Use NDS RomRenamer to Organize Your DS Game Library

NDS RomRenamer Tutorial: Preserve Metadata and Rename Safely

What it does

NDS RomRenamer is a tool that renames Nintendo DS ROM files in bulk using consistent filename templates while preserving embedded metadata (where possible) and avoiding accidental data loss.

Preparation

1. Backup files: Copy your ROM folder to a separate location.
2. Gather tools: Install NDS RomRenamer and a hex-aware file manager or tag editor (optional) for inspecting metadata.
3. Check ROM formats: Confirm files are .nds (and not compressed archives like .zip/.7z). If compressed, extract first.

Key settings to use

• Filename template: Use a template that includes unique identifiers, e.g., “{Title} ({Region}) [{ProductCode}].nds”.
• Preserve headers: Enable any option labeled “preserve header” or “keep ROM header” to avoid modifying internal ROM data.
• Use database lookups: Turn on online DB lookup (if available) to fetch correct titles, regions, and product codes—only if you trust the source.
• Dry run / Preview: Always run the preview mode to see name changes without applying them.
• Conflict handling: Set policy to “skip” or “append (1), (2)…” rather than overwrite.

Step-by-step

1. Open NDS RomRenamer and point it at your ROM directory.
2. Select the filename template you want; include product code or CRC for uniqueness.
3. Enable “preserve header” and “dry run/preview”.
4. Run preview and inspect at least a sample of results for correctness.
5. If using DB lookup, verify fetched metadata for regional variants or fan translations.
6. Configure conflict policy to avoid overwriting.
7. Run the actual rename.
8. Verify a few ROMs by loading them in your emulator or checking headers with a tag editor.

Troubleshooting

• Incorrect titles: Turn off automatic DB overwrite and correct titles manually for ambiguous cases.
• Missing metadata: Use CRC/product code lookup options or manual edits.
• Renamer modifies ROM header: Restore from backup and re-run with “preserve header” enabled.

Safety checklist

• Backup before changes.
• Use preview/dry run.
• Avoid bulk overwrite—set conflicts to rename or skip.
• Verify a subset after renaming.

Quick templates

• {Title} ({Region}) [{ProductCode}].nds
• [{ProductCode}] {Title} – {Version}.nds

If you want, I can generate a ready-to-use filename template list tailored to your ROM collection (e.g., region-first, code-first).
