A new rare video found on YouTube gives an explanation of the PS4 development kit, the machine developers use to test their game before releasing it to the public. Unlike your regular PS4, this machine can run any unreleased PS4 title; comes with more memory, and has more USB ports. The dev kit has the same menu as a regular PS4 with an additional “Debug Settings” which is shown in the video. The video also shows a Windows PC program called “Neighborhood” that allows you to control the PS4 from your computer and see all codes being run on the dev kit.
