R4 cards for 3DS

Since the first R4IDSN card works in 3DS console DS mode, R4I-SDHC.COM released its 3DS version red box card - R4I-SDHC 3DS in early March, 2011, by that time, they had found little progress in 3DS mode, discontinued another so called 3DS card. Now, this R4I-SDHC 3DS is known as R4 3DS among many users, just like what it means for R4 DS.

Up to now, their 3DS series flashcarts have developed from R4I-SDHC 3DS, R4I-SDHC 3DS V4.4, R4I-SDHC 3DS V4.5, R4I-SDHC 3DS V5.0 to current R4I-SDHC 3DS RTS. And only RTS version is in production now.


Note: At the beginning, R4I-SDHC 3DS was built with RAM chip open to the front sticker, and it could improve heat dissipation. Later vinyl package is introduced into this cartridge, the whole IC was integrated into back panel. This hardware version had to be changed since V4.4.0-9 system came out as they found that R4 3DS card had almost used up Demo game ID, R4I-SDHC 3DS V4.4 came out Last Dec. However, since 3DS system Ver 4.5.0-10, 3DS console boot-up will not only enquiry Demo game ID, but also detect flashcart save IC, which pushed them to release R4I-SDHC 3DS V4.5 and R4I-SDHC 3DS RTS respectively. R4I-SDHC 3DS V5.0 changes only its sticker marking into V5.0.

Kernel for these R4 3DS cards above are the same, they share the first official R4I-SDHC 3DS kernel.

R4 cards for DSi

R4 cards below are designed mainly for DSi XL and DSi, and red box R4i cards are popular among users ever since early 2009. With DSi system update, R4I-SDHC, R4I-SDHC V1.4, R4I-SDHC V1.4.1, R4I-SDHC V1.4.2/3/4 and R4I-SDHC V1.4.5 have been available from WWW.R4I-SDHC.COM. Now only V1.4.5 marking is on sale.

R4I-SDHC V1.4.5 is originally for DSi (XL) and DS, and it could be firmware upgrade for 3DS (XL). R4WOOD will have it updated with 3DS compatibility up to Ver 5.1.0-11.

R4I-SDHC V1.4.4/3/2 differ from their version marking on the sticker, no change for their hardware. And these three cards is compatible with DSi (xl) up to 1.4.4, no other firmware patch could get them updated for DSi 1.4.5.

R4I-SDHC V1.4.1 can only be used for DSi 1.4.1/1.4/1.3 and DS (Why my R4i-SDHC 1.4.1 can work on DSi 1.4.2 ?). R4I-SDHC V1.4 can only be used for DSi 1.4/1.3 and DS. The latest R4i above can only be used on DSi 1.3 and DS.

In early 2009, R4I-SDHC.COM also released GE / game engine marking R4i cards, not WIFI marking instead. They are of no hardware difference, just like GE R4I-SDHC V1.4 below and WiFi R4I-SDHC V1.4 above.

Those R4i with yellow star on the sticker share the same kernel for R4I-SDHC V1.4.5, while the one without yellow star is to be used its own kernel V1.11d released on 2012-11-21.
