== DETAILS - DS3 analog wasn't working mainly because I forgot to actually declare the axes in input/input_autoconfig.c when declaring the pad. Whoops. - I also moved the axis decoding logic to a more central place, because it clearly is not Wii U specific. - Removed some dead commented-out code == TESTING Can use analog inputs on both GCA and DS3. Tested in Mario 3 on Nestopia core. Haven't tested with any actual analog games, but I did confirm via logging that the correct ranges are produced.
