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! Hopefully this will help someone in the future who buys this flashcart.
