Hacking Is there any way to import save data from a DS cartridge to and R4 cartridge?

[Quadrotix]

Hello, I have obtained an R4 card and would like to know if there is any way to get my og cartridge data onto the R4 card. I have tried to use TWLsavetool on my 3DS which has CFW. When I did this I got the .sav file but it does not work when I put it on my R4 card. (I made sure it had the same name as the rom while keeping the .sav file extension)

Thanks for reading.

Try using that, worked for me. Set the output to the flashcart type or size you need.

Thank you so much! Everything seems to be working perfectly now so I can finally enjoy my 7 year old M&L:BIS save on an R4 card Again, thank you very, very much.
