There seem to be only us and jpn category? How about pal runs?

If PAL is exactly the same gameplay as US version just slower, then I don't see a reason for adding PAL category. As with most NES games to add PAL category, it has to have some distinguishing gameplay .

Well the title of the category is called specifically NTSC-version. Feels wrong imo to submit a pal run into ntsc category

However, that's how it works with most NES games. If someone really wants to have a run of the same just slower PAL version on leaderboard , then submits it to main US category, just in some cases it's not called "US" category, but simple Any%. Here, it is called that way to disniguish it from JP version.
