This is actually kinda relevant to something i read about recently-

TLDR; Speedrunners of Ocarina of Time will only run the japanese release because it runs at a higher framerate than the PAL release which therefore leads to overall faster RTA times. The japanese text is also faster to skip through. Seems to me that in order to get the best times, people play the version that runs the fastest. So, just run the PC version? Problem solved. I'm pretty sure Dark Souls runners swapped to PC too.
edit - this is my personal opinion ofc
