It runs via an exploit found about a year ago in WebKit [1] , and allows running custom code. It does not enable piracy, as that would require greater system access. It allows running simple applications, with severe limitations (can&#x27;t use native video out or controllers; workarounds employed are using an HTML Canvas for visual output and a Nintendo DS for control).<p>It is a very basic SDK right now, it is still in development and has a long way to go. Considering the exploit to run code only works on FW 1.76 (~1 year old), there presumably aren&#x27;t many people able to run code anyway.<p>[1] <a href="http:&#x2F;&#x2F;wololo.net&#x2F;2014&#x2F;10&#x2F;24&#x2F;webkit-exploit-confirmed-to-run-on-ps4-firmware-1-76" rel="nofollow">http:&#x2F;&#x2F;wololo.net&#x2F;2014&#x2F;10&#x2F;24&#x2F;webkit-exploit-confirmed-to-run...</a>
