    Hi everyone

    I was planning on getting some good games in physical formats such as TWEWY and Pokemon HG/SS. I've played these games in my computer for a long time but it came to my mind that when I get my physical copies of these games, I'll have to start all over again.
    Would there be some way or tool to inject the sav files created by the emulator into an actual cartridge?

    You'll have to use a DS save editor for CFW/Homebrew Launcher (TWLSaveTool:https://gbatemp.net/threads/release-twlsavetool-v1-0.412887/) then extract the save file, convert it to a save file extension supported by TWLSaveTool, (You can find these online) then put the converted save file on your SD card, go into TWLSaveTool, and load it in.

    That was quick af. I'll read about that tool right away. I really thought it was impossible to transfer your game data from HG/SS to an actual cart.
    Thanks a lot dude<3

    I'll write out the process right now. First off, make a save backup of the game and give it a name (by that I mean pick the number for it.). Then, grab your converted save, take out the SD card from your 3DS and replace the save backup with the one you have, but change it to the same name since TWLSaveTool doesn't let you customize the names and just puts something like save0001.

    So, even if the cartridge has never been used I still have to back up a save file?

    Yeah, so you can replace it with the one from the emulator.
