Download kernel from r4i card official web,Un-zip kernel,Copy all files into microSD card,insert microSD card into R4i card,insert R4i card in to DSi.
of course, new r4i v1.6 kernel can work on all below version of r4i card, including r4i v1.4 kernel.
Yes pokesav works on r4i
IF that is happening on your r4i there is something wrong with your r4i. It has nothing to do with the sd card its the r4i.
no
Only micro SD cards work with R4i.
the r4i v1.4 card is the old version, it can only work on dsi v1.4 and below console. No the latest r4 card for dsi is the r4i v1.4.5.
No, they don't sell R4i at Walmart but you can visit poshsystems.com to pick one up. They carry R4i-SDHC, R4i 3DS, R4i RTS and others. All of them work on the current firmware version of DS/DSi/3DS. R4i-SDHC or the RTS have the best interface in my opinion.
yes it does only if u have the latest firmware. Both the r4i sdhc 3ds card from r4i-sdhc.com and r4i gold 3ds card from r4ids.cn can support DSi european!
YES POKEMON BLACK WORKS ON R4i but on R4i Advance GO to r4iadvance.com WE DONT KNOW about Pokemon Black 2
R4i-SDHC or the RTS have the best interface in my opinion. They carry R4i-SDHC, R4i 3DS, R4i RTS and others. All of them work on the current firmware version of DS/DSi/3DS.
The R4i will work in all DSis with the 1.0-1.3 firmware. It will NOT work it your DSi has been updated to the 1.4 firmware.
Both M3i Zero and R4i card can work on Nintendo DSi V1.4.3 console.
