The SF2000 supports save states for games, but it bundles the save state data into a custom format including a thumbnail and metadata; this bundle can't be directly used as save state data for other emulator platforms (e.g., Retroarch). This tool allows you to extract raw save-state data and thumbnails from SF2000 save-state bundles, in case you want to use them with the same emulator on another device; it also allows you to take save states from another device, and convert them to a format the SF2000 can parse. Please note this tool is provided as-is; make sure you have backups of anything you care about before potentially replacing any files on your SF2000's microSD card! 🙂
This tool makes use of the pako JavaScript library.
This tool can operate in two main modes - you can use it to convert save states from the SF2000 format to raw save-state data (and optionally download the thumbnail), or you can use it to convert raw save state data from another emulator to the SF2000 format. Choose the mode you want, and follow the next instruction that appears.
