Lately, there's been an influx of newer runners of this game using emulators that do not run at the correct speed.
The NES runs at roughly 60.09 FPS. This is the correct frame rate. Most clones, FPGAs, or other options (The NES classic or Switch, for example) run at 60 FPS on the money; this is acceptable as well.
Any frame rates that are faster or slower are not allowed, and any runs submitted henceforth which are not at the correct speed will NOT be verified.
I recommend NEStopia for speedrunning. To maximize your visibility and legitimacy, I suggest enabling an input reader in the emulator settings (So we can see your inputs) as well as displaying the frame rate of the emulation. FCEUX is also an acceptable emulator. Other emulators may be acceptable, but I HIGHLY suggest you ask here first, otherwise you may end up grinding out a run of one of the hardest games ever made... only to have your run denied :(
Here is a google doc of general NES speedrun rules to follow: https://goo.gl/pYN6AR
(I highly suggest you capture your entire emulator window in OBS as well, in fact anything you can add to your recordings/streams that show us info about your emulation setup will help!)
