Ok, so if I did a run with the Japanese 1.0 ROM and submit it, do I submit it under the USA NTSC region or JPN region? Cause I've noticed runs under the USA region category have the jp text

Hey there, quick question. I've noticed with the Any% runs under the USA NTSC region that some runners have the japanese text, is that allowed? And if so, are they running the JPN version of the rom or what? Am just curious, thanks!
