Developed and delivered a 3DS Save Transfer Utility for the Universal-Team/db repository, enabling users to copy save files seamlessly between 3DS devices and emulators. Focused on utility development and 3DS platform expertise, the work introduced the SaveSync feature, which streamlines cross-device save migrations and improves the overall save management experience. The implementation relied on JSON for configuration and data handling, ensuring compatibility and ease of integration. Throughout the feature rollout, stability was maintained with no major bugs reported. This contribution addressed the challenge of manual save handling, laying groundwork for enhanced emulator parity and user satisfaction in save management.
