In Nintendo’s seemingly eternal battle against flashcart users and freeloading pirates, the company has released firmware 1.4.1U for the DSi. The official changelog contains nothing but a blurb that vaguely mentions “behind-the-scenes improvements” in regards to system stability.

Under that thinly veiled guise is another attempt at cutting off access to third-party applications, a move no doubt prompted by growing piracy concerns. Unfortunately, like usual, legal homebrew efforts take the brunt of the hit as a result.

Several reports have indicated that popular flashcarts have suffered a casualty due to this update. Models not working include, but are not limited to, the Acekard 2i, Supercard DSTwo, M3i Zero, iPlayer and DSTTi. Further, a GBATemp report claims EZ-Flash Vi, iSmart DS, Hyper R4i remain functional. At any rate, bearers of any of the previously mentioned carts will want to wait this one out until a solution is – likely inevitably – found.
