/* This is an X-include file which defines the mapping of keycodes used by
* libretro to keycodes used by RetroArch Netplay. The keycodes are different
* because the keycodes supported by libretro are in discontiguous blocks,
* which would create gaps in the input data, requiring more space and more
* network bandwidth to represent them.
*
* If you want to add a new keycode, make sure you add it to the END. The order
* that the keys appear in this file defines their indices in the netplay
* protocol, so adding a key in the middle will break backwards compatibility.
* If you want to clean up the order and thereby break backwards compatibility,
* make sure you bump the protocol version in netplay_private.h.
