Mixing R4 software and hardware

Hey there I would like to know if using the R4i software on my R4 to play with my DSi is not going to work. I only ask because there is no mention of this anywhere that I can find and would like to ask people who have an idea about this sort of thing before totalling my R4. ???
Thankyou. :D

R4i is different hardware to the R4. R4 will not work in a DSi, nor will it run R4i software.

nah it wont work , i tried :P you'll have to get an R4i to use with the DSi

Thankyou! ;D
Any suggestions as to where to buy an R4i?? I don't really know which websites to trust (I need UK delivery).

I've ordered from ConsoleSource.com on various occasions and as of yet, have not been let down.
I also have a friend, or rather, more of an acquaintance who also ordered an R4 from them and had a clear transaction.
Though, i'm not positive on the UK shipping, feel free to check.
