There are heaps of reasons. One is that the microSD isn't loaded. Second is that if your r4i memory is full. Or the most common reason is because Your R4I is damaged or YOUR dsi has a virus.
**********You go on Nintendo ds settings and go on date and change the date to a previous date.
If your R4i is displaying "Danny Phantom Urban Jungle" but gets stuck on a loading screen, it could indicate a few issues. The ROM file may be corrupted, incompatible with your R4i firmware, or the firmware itself may be outdated. Try re-downloading the ROM from a reliable source, ensuring it's the correct version for your R4i, and check if your firmware is updated to the latest version. If the problem persists, consider trying a different ROM or checking for issues with your R4i hardware.
You can format the MicroSD card, and re-install the latest r4i sdhc kernel. Mostly, the problem can be fixed. It it still not work, you can contact the reseller for replace. The connection may be not well. just make them connect firmly.
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.
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 pokesav works on r4i
it seems R4i has better capabilities than acekard 2i but alot of R4i's are fake.
