Interrogating a Sony PlayStation 2 DualShock 2 controller; I've yet to figure out why SDL2 reports that the DualShock 2 has five axes (although my PlayStation-to-USB adapter might be to blame), I've yet to figure out a solution – which doesn't involve a ⅓ axis dead zone – to the problem of the thumbsticks on the DualShock 2 not always returning all the way to the origin when they're released, and I last touched a DualShock 2 a long, long time ago so I'd forgotten that the D-pad is disabled in analogue mode :/

I recently rebooted development of a project I tried to develop for the Ludum Dare 20 contest held in April 2011, the theme of which was “It’s dangerous to go alone! Take this!”

As the project will require a controller with an analogue stick to play I’ve begun to develop a utility to interrogate the capabilities of various controllers – and as I feel that the SDL2 documentation is lacking with regards to the joystick support offered by that library I’ve posted to my blog the source code to the third version of that utility, for the benefit both of myself and of others.
