can anyone tell me do i need to use something specific to put games on my R4 card from a mac?, i have some from nds roms and they seem fine but when i transfer to the card and put it in my ds they start to load and then say cant find saved data? Thanks
The r4ds team is no longer making firmware for the r4. I think the last official firmware was 1.18. Some newer games just don't work. They have different methods for saving your progress. Try some different roms.
