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.
you can buy it from stores like target,best buy,and walmart Good Luck!
of course, new r4i v1.6 kernel can work on all below version of r4i card, including r4i v1.4 kernel.
For r4i gold from r4ids.cn, the latest firmware is wood r4 V1.46; for r4i gold V2.0 from r4ids.com, it is the AKAIO V1.8.6 kernel; for r4i-gold card from r4i-gold.com, the latest software is r4i V1.71b.. Now it is already wood r4i v1.51b.
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.
You can buy R4i cards online.
No. R4i and R4 are not illegal. R4i and R4 are only illegal if they have games on them.
r4i gold and r4i sdhc card are most popular in players. both of them can support 3ds, dsi and ds lite. but personally, I think the r4i gold card has better compatibility.
Yes pokesav works on r4i
it seems R4i has better capabilities than acekard 2i but alot of R4i's are fake.
The R4i Gold is a fake card released to try and take advantage of the R4i selling so well worldwide. R4i sdhc and r4i gold card are different flashcard. they are similar in functions. But different in package. they use difference kernel. Both of them are popular in Players currently.
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.
This is a very weird question.
