I've created a modified version of chocolate-doom without the basic menu options (I've removed them from chocolate-doom/src/doom/d_menu.c) and with a UDP socket that can receive new event_t and post them with D_PostEvent. All this code is located in chocolate-doom/src/twitchdoom.c and chocolate-doom/src/twitchdoom.h.
