You can check it out here: https://savefileconverter.com/#/flash-carts
It can handle every kind of flash cart I'm aware of, plus the emulators and cores that are built in to some of them (e.g. GB on a GBA or N64 flash cart, or NES on a Genesis Everdrive). The only type of flash cart that's missing is DS because that seems to be handled well by https://shunyweb.info/convert.php
Everything is free and open source: https://github.com/euan-forrester/save-file-converter
I've also got a Discord for the site here: https://discord.gg/wtJ7xUKKTR
Did I miss anything? Does something not work? Got other suggestions? Please let me know!
