I found my answer it is allowed due to being slower lol.

Hello guys, I was thinking about picking up DQ V to speed run on the SNES but i really want to do it on the patched english version. What would be the rules on submitting that run or making that category. I know it isnt an official release which is why im asking. And of course i could learn the JP version but it is always nice to speed read the text as well. Thoughts, concerns, comments appreciated. Thank you
