I have r4i sdhc rts from r4i-sdhc.com it says it cant be restored after use, do i download the ds or dsi injector? I have a ds lite and another 3ds but it says dsi wont let you restore so i am flashing with a ds lite and it says it cant be restored, is there any way because my friend has the same flashcart so can i make a backup from his or is there any way to restore it because i really want ntrboot and be able to use it as a r4 after, if the answer is no is there any .cia that can play nds games instead without a flashcart?
