Based on on when I watched your run and did a RTA timeing, it was 9:38 which is slower than my terrible sub 9 time of 8:xx which means I do not think you should be calling that run a WR.
I'm just reposting what I said on the discord.
You, yourself, wanted in-game time to become legalized and advocated for it along with me and Yoshino, and in fact, were working on one that removed loading times entirely. We decided that the game should be purely a measure of skill and not a measure of how well your pc can load the game. Since the in-game timer is legalized it is allowed to be used currently, and I trimmed down your record video and your in-game time was still slower than my time. I edited it and cut out more than I should have and it ended up with a 7:53 which is still slower than my 7:39.
