The speedrun.com page for Perfect Dark is only for emulator speedruns of the game, which basically nobody cares about. There are discords for the XBLA version of the game (https://discord.gg/cTYmmv2), and for The-Elite.net, which is the official host for Goldeneye and Perfect Dark speedrunning exclusively on the original N64 hardware (https://the-elite.net/discord).
