smea got his start making video games for closed consoles like the Nintendo DS using whatever hacks were available at the time. At some point consoles started getting actual security features and he transitioned from simply making homebrew software to making the jailbreaks that let people run it. He's best known for his work on the Nintendo 3DS and Wii U but has also done exploitation work against high profile web browsers and virtualization stacks.
