I recently purchased a new DS (the original, not the SDHC) from Hong Kong which came with a free R4 SDHC card. I decided to give this one to my brother so we didnt have to constantly share the same one. Thinking that I could just copy and paste all of the files on the old R4 to the new one, I deleted everything the new R4 had, including the system files. Since then, whenever I load the new R4 on a DS it stays on the loading screen and doesn't change. Any help at all would be appreciated, thanks!
