What is ironhax?

Ironhax is a software exploit that allows users to run unsigned code on their Nintendo 3DS handheld gaming console. It was discovered by Smealum, a well-known hacker in the 3DS homebrew community, and released publicly in August 2015.

To use Ironhax, users must first install a custom application using the Nintendo 3DS's built-in web browser. This application then exploits a vulnerability in the 3DS system software to grant the user access to the console's memory. From there, users can run homebrew software, emulators, and other unsigned code.

Ironhax is one of several software exploits available for the Nintendo 3DS, with others including OotHax and Menuhax. These exploits have been controversial in the gaming community, as they can be used to run pirated software on the console. However, they are also used by legitimate homebrew developers to create custom applications and tools for the 3DS platform.
