R4i 1.4.2 Update

UPDATE 4/JUNE/2011: The information on this page is now out of date.The R4i Team have released a firmware fix for the R4i 3DS card, and it now works on DSi 1.4.2! Please click here for a step-by-step guide to updating your card.


On the 11th of May 2011, Nintendo released a patch for users of the Nintendo DSi and DSi XL consoles. This update changes the version of the firmware from 1.4 or 1.4.1, to the newest 1.4.2 version.

When you are either in the online store and go to the System Settings menu of your DSi, you will be presented with the following screen.

If you currently use an R4i SDHC card or an R4i 3DS card, do not upgrade your console to the latest firmware via Nintendo’s system date! The update will block your flash card from functioning on your DSi console. The R4i team are infamous for not being able to ‘upgrade’ their flash card’s firmware to be compatible with Nintendo updates, instead releasing ‘new versions’ of the card for people to buy. Therefore, once again, do not upgrade your DSi console if you own an R4i SDHC / R4i 3DS card!

While there has been no official announcement from Nintendo regarding this update, it is not difficult to guess why the update has occurred. Later on in May a software update will be made available for the Nintendo 3DS as well. Within this update is the 3DS eShop, where users will be able to buy games and also transfer DSiWare and games over from their older DSi consoles. The new 1.4.2 update for DSi consoles likely facilitates this transfer to the Nintendo 3DS. Naturally, the update has also currently rendered all DSi-compatible cards inoperable.

Updates are likely to be available in the near future for firmware-upgradable cards such as the Acekard 2i, M3i Zero and EZFlash Vi cards. However, there is no definite time frame for when these updates will be available. Cards that are upgradable are notably more expensive, so be prepared to pay a bit more if you wish to buy a high quality card. The R4i SDHC / R4i 3DS is a genuine AND reliable card, but the reason it is cheap is because historically the firmware was not upgradable. This may well be the case here, and more news will be updated on this page as and when possible.

In the mean time, please visit the Where To Buy page if you would like a flash card for your Nintendo DS / DSi / 3DS console for a list of stores that sell only genuine cards. Beware where you buy from and never buy fakes – we vet all stores (and our list may sometimes change to reflect this!) to make sure they only sell authentic cards and provide adequate customer service.
