all the i compatible karts will work on DS PHAT, DS LITE and DSi
so it will WORK

however, if your friend had updated his/her DSi to the 1.4 firmware
i will only say GOOD LUCK (it could work or doesn't work)

 

Ok thanks... so if they have updated to 1.4v what r4 card should I order? and if that works on my dsl will it work on my friends dsi?

 

I've heard great things about the m3i zero, though I don't have any personal experience with it. I do have experience with the R4i-SDHC (red box), and I can say that as of yet it does not support DSi with 1.4 firmware. The best thing you can do is pawn it off on someone with a DS lite with no intention of upgrading to a DSi, and finding a card that already supports the 1.4 firmware. If your friend hasn't updated, and you set them up with the R4i-SDHC, and they turn out to be unable to overcome the 1.4 firmware issue, you'll effectively be making your friend choose between the flashcart, and access to the DSiWare store, as well as the facebook integration included in 1.4.

 

You know, through mid-July, they had been releasing updates at least once a month. It stands to reason that the 1.4 kernel is the reason for the interruption in their regular updates, and that as they had also been updating their non-DSi card's kernel as well, they'll probably continue releasing kernel updates for ROM compatibility issues.

 

All is good the R4i sdhc works for my friends dsi only because its her dads dsi and he doesn't use facebook. What do you guys think of the R4i Gold that works on 1.4v?

 

I think the r4 sdhc 1.4v upgrade is already out just saw it on the R4i-sdhc.com. The R4i gold i ordered (haven't received it yet) says it works with 1.4v but which do you think is better R4i gold or R4i SDHC and whats the difference anyway?
