Yep, even going way back, there are differences between speedrun times for Ocarina of Time on N64, Ocarina of Time on GameCube, Ocarina of Time on Wii VC, and Ocarina of Time on NSO. And that’s also not factoring in the native PC port recently assembled by the community.

And that’s why speedrun leaderboards always factor in game version/region and platform when measuring runs against one another.
