With the set-up above, two accessibility switches are all that are needed to browse the Playstation 3 menu system. From there you can freely switch between the likes of the BBC iPlayer, Netflix, photo albums, MP3s, the Playstation store, the internet and a range of one and two-switch playable games.
The set-up requires a PS3 connected via a Cronus adapter to a Windows PC, running JoyToKey and Bullseye with special profiles that you can download here. Two switches are connected to a C-SID (Button 1 and Button 2) but any USB connected joystick should work just fine too.
