This port, called Open Ocarina, now features an experimental mode that supports 60 FPS gameplay. Despite still being experimental, and with a few bugs here and there, it already seems to work nicely, judging from the video shared by zel on Youtube.
The Legend of Zelda: Ocarina of Time Open Ocarina native PC port can be downloaded from GitHub. The repository does not feature any of the assets necessary to build the ROM for obvious reasons, so it requires a prior copy of the game. The Legend of Zelda: Ocarina of Time was originally released on Nintendo 64 before getting ported to different Nintendo systems and getting finally remade for the Nintendo 3DS.
