its like this, i'm using a mirco sd card as i didnt have a memory card that came with my R4, so i decided to test the card. When i put games in it , put it in my DS, turn it on, it said " could not find DS_MENU_DATA" so i decided to come here to try finding that data. i think i found it, and when i did, i downloaded it and it came as a binary file. i tried to put that in my DS and the same message came up " could not find DS_MENU_DATA"
so i dont know what to do as i dont think i can get the data as most things are exclusive to windows.
