The save data could not be accessed. Please turn the power off and reinsert the DS card. This is what shows up on a game my daughter has played several times and now she can not play it. This has shown up on Bolt, Let's Draw and a few other games. We have an original R4 card with the 1.18 kernal with the 1.34 patches and ys menu and all that other stuff to get new games to work. We've tried wood r4 but she wanted a theme that was not available for the acerkard2. Anyway if there is afix on this please let me knnow.
Try the arm7 & arm9 patch method or use dscovered and wood r4 as loader so u get to launch your games from covers although with the compatibilty of wood r4 - tinyurl.com/r4stillalive
