The developer always wanted a more streamlined way to transfer save files between the 3DS and PC, so he created a simple tool to share with the community.

This lightweight GUI application built in Python connects directly to FTPD on the console without requiring additional tools on the 3DS - users simply need their existing FTPD client.

The tool enables one-click downloading and uploading of save folders while automatically creating timestamped backups before overwriting anything, ensuring save files are never lost even when mistakes occur.

Features

One-Click Transfers: Simple "Download to PC" and "Upload to 3DS" buttons.
Automatic Backups: Always creates a backup of the destination (either PC or 3DS) before transferring files.
Dynamic Categories: You're not stuck with just 3DS/NDS/GBA. You can add, name, and remove your own save categories for different emulators or systems with custom paths.
Network Scan: If you don't want to type the IP, you can leave the field empty and it will scan your network for the 3DS/FTP-Server.
Works with Checkpoint: Designed to work with the folder structure created by Checkpoint for 3DS games, as well as simple folder structures for NDS/GBA saves. For 3DS Games: Please use Checkpoint on your console to export your save files first.

How to Use

Prerequisites:
- A 3DS console with Custom Firmware (Luma3DS) and the Homebrew Launcher.

Setup:
