Emulation Ninja supports both quick imports and structured library ingestion.
Import options
- Single-system import for quick validation.
- Organized folder import for full library onboarding.
- Migration-style import when folders are already grouped by platform.
Tips for clean imports
- Keep ROM files in stable folders before scanning.
- Re-scan after adding many new files.
- For MAME, expect merged/non-merged set handling.
