Developer Euan Forrester recently launched a web-based tool that lets you convert save files from multiple retro platforms. It works by first converting the source save file to a “raw” file that’s often compatible with software emulators. You can then take that raw file and convert it back to any of the other formats supported. This really is a handy tool for people looking to continue their game across multiple platforms and to ensure your save game is backed up in a way that’s future-proof.

I’m a big fan of projects like this and was thrilled with the Genesis converter that came out in 2020! This brings things to a whole other level and there’s even plans to expand it further! Check out the github for instructions and more info…or just skip to the main page and give it a try!
