I got a new SD card and I don't have the cd anymore, but when I put in my R4 it says _DS_Menu.DAT not found.
When I download the kernal from the R4 website it comes as a "rar" file. When I put the rar file in my R4, it still says _DS_Menu.DAT not found. I have a mac computer, does that change it?

Please help me! Thanks!
