i think Urinal Mike might beat it

NTSC-J is the fastest version for speedrunning. Loading times and text make it faster than NTSC-U and PAL for all categories. However, it is notably more difficult; the sixth mission in Sirena Beach requires a much greater percentage of goop to be cleared before allowing the player to proceed, and a more difficult strat for EYG is required on Japanese (although it is also sometimes used in English as well).

Felt like posting here because forum is empty. But, ヤマた is best and will get all WRs ［ｏ］
