Does regular R4 for DS work for DSi? because i lost my friends, and i'm probably gonna give her mine. and she has a DSi....so yeha.
http://www.dealextreme.com/details.dx/sku.22584 R4i is the one that works for DSi. Although R4 doesn't release updates anymore. So if you download new DSi software that blocks it, you're screwed. I suggest Acekard 2i. http://www.dealextreme.com/details.dx/sku.18728
