What is Save File Converter?

Updated

Save File Converter (savefileconverter.com) is a browser-based tool for converting retro console save files between formats. It targets people who move saves across emulators, flash carts, original hardware, and FPGA systems like MiSTer — for example, turning an .srm file from an emulator into a .sav file a flash cart can read, or converting a GameShark save into a standard format. The site requires JavaScript to run; with JavaScript disabled it only shows a notice asking you to enable it.

What it converts

The site describes support for save files across a wide range of retro platforms and devices:

  • FPGA and flash carts: MiSTer, Saroo, various flash cartridge formats
  • Handheld and console families: PS1, GameCube, N64, Dreamcast, Sega Saturn, Sega CD
  • Cheat devices: GameShark (.sps and .gsv), Action Replay, DexDrive
  • Official and emulated services: Nintendo Switch Online, Wii Virtual Console, Retron 5
  • Emulators and online emulation sites: including save states exported from browser-based emulators

Core capabilities

  • .srm ↔ .sav conversion — the most common need when moving between emulators and hardware.
  • GameShark format handling — converting .sps and .gsv files.
  • PSP save decryption — decrypting PSP saves so they can be read or reused elsewhere.
  • Save state conversion — turning save states from online emulation websites into standard save files.

Beyond conversion

The site also offers guidance on related tasks:

  • Downloading save files
  • Erasing cartridge saves
  • Copying saves to and from original hardware

Is it worth using?

If your task is moving a save between two of the supported formats — emulator to flash cart, GameShark to standard, PSP to readable, or online emulator state to a real file — this is a purpose-built tool for exactly that job. Two practical conditions to check before relying on it:

  1. JavaScript must be enabled, since the converter runs in the browser.
  2. Confirm your specific format is listed before starting, especially for less common flash carts or cheat devices.
