About This Tool

Welcome to the ultimate Save File Converter, a modern tool designed for the retro gaming community. Have you ever spent hours on a game using an emulator, only to find your save file is incompatible with another emulator or a real hardware device like a MiSTer FPGA? This tool solves that problem. It allows you to effortlessly convert your game saves—such as `.srm`, `.sav`, `.mcr`, or `.eep` files—between various formats for systems like the SNES, Genesis, PlayStation, and N64. Our converter handles the complex byte-swapping, padding, and structural changes required, so you can seamlessly continue your progress across different platforms. It's built to be fast, private, and incredibly easy to use.

How to Use

1. Upload Your File: Simply drag and drop your save file (e.g., `gamename.srm`) onto the designated area, or click to browse and select it from your computer.
2. Automatic Detection: Our tool will analyze the file and attempt to automatically detect the game system and format. You can adjust this if needed.
3. Select Target Format: Choose the desired output format from the dropdown menu. For example, if you're moving a save to a MiSTer, you might select a MiSTer-compatible `.sav` format.
4. Convert & Download: Click the "Convert File" button. The conversion happens instantly in your browser. A download link for your new, converted save file will appear immediately.

Tips for Best Results

• Backup Your Original Save: Before converting, always make a backup copy of your original save file. While our tool is reliable, it's a good practice to never work on your only copy.
• Check File Extensions: Emulators can be picky. After downloading your converted file, ensure its name and extension (e.g., `.sav`, `.srm`) exactly match what your target emulator or device expects.
• File Size Matters: Our auto-detection feature uses file size as a clue. For example, a 131,072-byte file is likely a PS1 Memory Card. If detection fails, ensure you've selected the correct source format manually.
• Privacy First: All conversions are performed locally on your computer. Your files are never uploaded to a server, ensuring your data remains 100% private and secure.
