L.S. I got two games that don't want to work on my DS, Race driver Grid and Sonic Chronicles. I already updated the system software of my M3DS real with 4128G6_M3DS_R-E36 and put an working arm7.bin in these games. But no result. On some other games it worked wonder well. Only these two won.t work. My DS told me that the save data could not be accessed. Please turn the power off and reinsert the DS card. With the above solutions it has to work, so why not. Can you help me???
