If the "load NDS through NDS cart" feature doesn't work, I guess you should look in to uninstalling fwnitro. Yeah but i cant uninstall it cause it wont boot my R4 and since im 13 i cant order a gba flash cart =( Not sure what your age has to do with that, but if you have an R4, why not get a GBA flash cart from the same place you got the R4?
