i have tried r4i upgrade website but when i put them on it just goes all black get anyone help?

and go to gbatemp and look for the one you have
(get an ackeard 2i)

my r4i is a r4i gold!

ummm try www.ndsthemes.com
and http://www.r4ids.com/r4i-download-e.html
They're near the bottom. Also, you may need to change the language to chinese to download some of them, otherwise you'll get an error when you try to download the skin.
you can try to look for r4i gold skins here http://filetrip.net/c119-R4M3-Skins.html via gbatemp

the only one that works is r4i.com or wateva thanks BTW!
