You download the R4 menu off the website, what do you think?
I get my codes in a special menu on my R4
Ds starting system
This is an easy one. Go to the r4 site and download the latest kernel under the download section. Put all that on your microSD the plug it into the DS.
It's possibly a fake. Genuine R4 cartridges haven't been made since 2007.
take the memory card out then in
An r4i can let you back up the games that you already have (please note an r4i only works on a dsi and dsi XL if you do not have a dsi or a dsi XL you will have to get a normal r4 but do not be sad a normal r4 cando everything an r4 can).
you can't. download the game again
you need to download a kernel off the official r4 website. Mine uses kernel 25 and I got mine a couple of weeks ago.
not for the original r4 but if you have the r4 ultra or r4 sdhc or some other r4s then yes
