bottom part is duplicate of libretro#161, with a 20$ bounty as of this writing.

at least for KoroKoro, its only the libretro port that has the input broken. it happened during the introduction of multitap code. building the standalone or a libretro port from the master commit from this main repo does not have the input issue (for the said game at least).

moved issue to libretro#271.
