You will have to buy R4i, because R4 doesn't work on DSi.
No you can't use the original R4 on the DSI, but there is something called R4i that's supposed to work on the DSI.
you can use a r4 for ds lites but with dsi's there is a different type of r4 sorry i dont know the name of it
No, the R4 for the DS will not work on the DSi
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).
No, the DSi's anti-piracy functionality stops R4's being used.
You should get a Dsi action replay it rocks totally! (R4 sucks)
All r4 3ds cards can directly support dsi console. No need to do anything. Just insert the r4 3ds card into the dsi console, it can be read.
You either hack it.. you can use a R4 and download ROMS. or you connect your dsi to the internet and buy them in the dsi shop... for a normal ds well you can buy an R4 online... hope this helps!!
yes
Yes, that is what the R4 is made to do.
This is not a simple answer... let me explain: If you have updated your DSi to version 4.0 then you CANNOT because this update will have blocked cards such as R4 etc. If you HAVE NOT updated your DSi to version 4.0 then there are two explanations. The R4 card will not work because they only work on NDS/NDSLs. However, you can use cards built for DSi like the AceCard and the DSTTI card.
Only if you buy a R4i DS.If you have DSi Firmaware 1.4 , you will need to make sure the box says "v1.4!" Original R4 DS card can't work on DSi. There are many r4 dsi card in the world. which can run on Nintendo DSiXL, DSiLL, DSi, DS and DS lite.
