/**********************************************************************
SNK Neo Geo Kizuna 4Players Controller emulation
The NEO-FTC1B board is a JAMMA splitter, including input
multiplexing, video buffering, and audio amplification. It
requires an MV-1B or MV-1C system for the output header.
There are unpopulated locations for four 15-pin D connectors,
so it could theoretically be used with AES joysticks. It
won't work with mahjong panels because the outputs aren't
demultiplexed.
