The Nintendo 3DS firmware update 11.15.0-47 has rolled out. The new update is apparently focused on patching an exploit used to pirate games.
Twisted Voxel reports:
According to the changelog that was shared by Nintendo, this new firmware update is only for the stability improvements to the handheld. It doesn’t actually add anything to the software features.
According to reputable homebrew developer, OatmealDome, this patches something for the Nintendo 3DS browser which suggests that it could be related to an exploit that was fixed for piracy.
The Nintendo 3DS is well into its twilight. The only updates that fans should really expect at this point are ones that patch exploits.
