I was submitting a run, and couldn't select PAL... what's that about?

idk but its there for me

Is that for these leaderboards? That's the background for Super Mario World 2, not Super Mario Advance 3. Moreover, the category Warpless doesn't exist here. (there's 'Any% Warpless' for full-game, though)

oh gba has no regions. i totally didnt pay attention to which game this even was sorry

So should I just choose USA, then?... You're a Moderator, can't you add PAL?

theres no pal just select USA or whatevers there
