RTA Guide/Timing Guide
Super Mario 64 follows the JRTA timing convention, meaning runs start on console reset/power on. These may look slightly different based on which platform you're using and how you are restarting the game. This page aims to serve as a guide for timing your SM64 speedruns and/or retiming your runs using the raw recording or twitch/youtube VOD.
Timing Conventions
This section explains how to time your runs in real-time using splits software. It is important to remember these programs have no effect on what the time of your actual run is and they only exist for convenience (i.e. forgetting to split when you grab the star won't make your run any slower). However, following this guide should make it so that it is as accurate as possible.
N64/Emulator
For runs done on Nintendo 64, the first frame of the logo appearing is used as a frame of reference to "sync" runs which use the reset button and the power on switch. The convention is that the first frame of the logo appears is 1.33 seconds into the run.
Autosplit64
There is an autosplitter that many people use, which can detect resets, door touches (x-cam), the end of the run as well as the usual fadeouts after stars. It is strongly recommended to set this up as it is very convenient and accurate and will save you (and the mods) a lot of headache.
Manual Timing
For manually starting the timer, you can use the offsets so that you can hit the power on switch/reset button at the same time that you start your times. Keep in mind these offsets are still prone to human error and possibly differences in setups, so you might want to test and tweak these offsets to match your setup. For power on a typical offset is to start your timer at -1.00.
For using the reset button an offset between -1.20 and -1.30s is standard.
Wii VC
For Wii VC, the run starts on the first frame of the black screen before the Classic Controller text. Generally, you can start the timer at 0.00 and hit the reset button the Wii at the same time. Restarting with the WiiMote is not recommended as it is inconvenient and the black screen before the controller text lasts longer.
Wii U VC
For Wii U VC, the run starts on the first frame of the black screen before the Super Mario 64 logo.
