SM64 IGT to Real Time Converter

This web tool helps SM64 individuals easily convert their single star times from in-game time (IGT) to real time. You can view a live version here.

Real time is calculated using the following formula:

real_time = (in_game_time * 60 + buf_at_end - buf_at_start + num_fadeouts * 4 + num_ttm_slide_entries * 148) / (60000 / 1001)

Why is real-time is greater even without any lag?

SM64 in-game time is tracked at 60 frames per second, while the actual output is at 59.94 seconds. This means even without lag, the in-game timer is still slightly different than real time.

For more information on SM64 speedruns and links to the community Discord server, etc., check out the Useful Resources document.
