Introduction
The R4-III SDHC Upgrade is a slot-1 flashcart by R4IIISDHC.COM that supports the Original DS and DS Lite models. It is a clone of the U2DS, which is also a clone of the DSTT because they share similar traits such as the shell and circuit board. It supports SDHC cards with a maximum capacity of 32GB; however, a 2TB SD card can be used if properly formatted to FAT32. TWiLight Menu++, YSMenu, and AKMenu Next kernels will all function perfectly with this card; however, it is strongly advised not to use the official TTMenu kernel because it can BRICK it.
Originally, the R4-III website provides a modified build of TTMenu with most, but not all, instances of DSTT names removed. Although, it has the 'fake killer' code removed, we do not recommend using it for compatibility reasons, and that there are better alternatives.
The kernel file that the flashcart looks for on bootup is
R4.dat instead of TTMenu.dat.Hardware Specifications
