My dad recently bought me the r4 for the 3d ds in china. When I got it it was already set up and it worked fine except it was in chinese and the games were dumb. This cause me to delete everything on the chip and in stall the english version from the r4 site. However, now when i plug the chip back into my ds, it just shows error on the top screen and a pic of a distressed sd card -.-. Does anyone know to fix this problem. BTW i have mac. I'm not sure what difference it'll make, but i might as well say that.
