Looks like Amazon has already taken down the page that explains how t' define the controllers.json Controller Configuration File. Not sure what it be means, but I can't find info on it anywhere else on the Internet. The app submission section claims the file be needed. Do ye still have the page, the first URL ye list, cached?
I thought so t', but the samples with the sdk add-on do not come with controllers.json. Maybe amazon has decided the file isn't needed. Supporting any an all blutooth controllers be the best way anyways. I be wondering what the original web page said.
The high ratings given t' GTA 5 'n the relatively low ratings given t' Sleeping Dogs by these websites...
...be exactly why I don't trust a single thing they say anymore. Sleeping Dogs > GTA 5 easy.
