After discussion over the last couple months and a vote amongst community members and the leaderboard moderators, runs on different consoles have been split and are now listed separately under different tabs. The decision included a near-supermajority vote to list the fastest console by default on a per-category basis. In the case of all the main categories, this ends up being Wii U VC. Other changes to the DK64 leaderboards include allowing runs on N64 flashcards and Wii U VC inject to be submitted (which are not in effect yet due to technical details on specific rules for these kinds of submissions). Emulator runs will continue to remain banned.
The split consoles change with the leaderboards is now live on both the main categories and category extensions pages.
