I have a fake green r4. By mistake i pressed select and deleted some system files, titled '?'. The next time I started my dsi and r4, i could just see a white screen. now i dont know how to replace those system files. the following was writen on the front of my r4 cartridge: Wi-fi R4i v-1.6 Revolution for DS (DsiLL/NDSi/NDSL/NDS) www.ndsiLL.net I checked out that site but that software was of no use. I checked out some other sites also, but in vain. Someone plsease help???
