What separates the R4i Gold from the other DSI cards is their support for the latest firmware from Nintendo. The new updates for the R4i Gold from the R4i team allow users to get the most from their consoles, and with constant updates from the Nintendo Corporation constant work is needed by the R4i team to ensure the R4i Gold continues working. As of late there have been two main updates v1.4.3 and v1.4.4 which have both been fully supported by the new R4i Gold cards.
Other versions of the R4i Gold such as the R4i Gold 3DS support, as the name would suggest, the newest 3DS consoles from Nintendo. Possibly the best all round device on the market for DS consoles, the R4i Gold 3DS supports every current version of the DS console out there, which includes the DS, DS lite, DSi, DSi XL and 3DS consoles.
