Ok I got it to work: I went to r4ids.cn ,clicked on downloads, scrolled down to Newest WOOD R4 kernel, clicked on download. I unzipped the file (Wood_R4iGold_V1.64.rar), then dragged the _rpg folder and the _DS_MENU.DAT file to the root of my SD card. I then made a folder named GAMES (at the root of my SD card aswell) and dragged some downloaded roms into it (ex: 2696 - Kirby Super Star Ultra.nds). Ejected sd card, placed it into R4 flashcart, inserted into 3DS, clicked on the game slot/cart icon, and it works! Just choose a game and play!I have the exact same card but I can't figure out how to run DS games on it. Is there a specific kernel I need to download for it? I can't find any info for this specific card (R4i 3DS Gold Plus) Any help would be greatly appreciated!
Hopefully this will help someone in the future who buys this flashcart.
