orry for the rudimentary question. If I want to do a speedrun on the PS4 version, is there a problem in the rules if I replace the HDD with an SSD? (I asked this question because it is not clearly stated in the "View rules" on the leaderboard)

問題ないと思います。 記録の概要に記入しておいていただければと思います。

No problem I think. It is helpful that you add it to the description of the run.
