I put the wood kernel on the card, moonshell 2, games and media folder, wood in the games folder, games in the games folder.. tried this on 2 cards and when i put it in the dsi xl all i get is a white screen.. I have NEVER had any problems with modding anything, i do not understand what can be wrong.. It says there Alex on the menu and when you hit it the screen is white.. nothing else, it just freezes..
If the URL on the packaging is r4idsn.com then it should be compatible with your R4. Make sure the wood firmware is on the root of your microSD, NOT in any folder
