// license:BSD-3-Clause // copyright-holders:Fabio Priuli /********************************************************************** Nintendo Family Computer & Entertainment System Joypads The original Famicom had two hardwired controller, with the second controller slightly different from the first one: it featured no Start nor Select buttons, but had a built-in microphone (with very limited capabilities, since it basically only detected two states: something blowing into it / nothing blowing into it) for some games to react to users "talking" into it Crazy Climber Pads are not really a kind of separate controllers, but just a couple of small sticks to be put on top of d-pads of the regular controllers. Users should then control the game by using both controllers, turned 90 degrees, as a couple of dual sticks like in the arcade control panel. However, we emulate them separately so to map the controls to a friendlier default. The Arcade Stick we emulate is a controller (apparently manufactured by Hori, but possibly licensed by Nintendo, since it use the official logo and brand) which fits into the expansion port and allows to daisy chain a second controller to the first one, to play 4players game (an image of such connection is shown e.g. in Nekketsu Koukou Dodgeball Bu manual) **********************************************************************/ #include "joypad.h" //************************************************************************** // DEVICE DEFINITIONS //************************************************************************** const device_type NES_JOYPAD = &device_creator;
