SM64 has glitches like BLJs out from 3DAS and Galaxy does not have a glitchless category so it's not possible at the moment.
Opinions on 2P now are way different then 5 years ago with a lot of top runners and players getting better at 2P and now accept it because a lot of people prefer it and it's faster. While the community does have some disagreements on whether it should be allowed or not usually the reasons are different then people running this game 5 years ago. The people who have opinions about this are mostly by people who run or have a lot of experience with the game where they usually have a more valid opinion. If you had experience you would have a better and reasonable opinion about this on whether you agree with a 2P split or not.
Mae hen wlad fy nhadau yn annwyl i mi, Gwlad beirdd a chantorion, enwogion o fri; Ei gwrol ryfelwyr, gwladgarwyr tra mâd, Tros ryddid gollasant eu gwaed. Gwlad, Gwlad, pleidiol wyf i'm gwlad, Tra môr yn fur i'r bur hoff bau, O bydded i'r heniaith barhau. Hen Gymru fynyddig, paradwys y bardd; Pob dyffryn, pob clogwyn, i'm golwg sydd hardd, Trwy deimlad gwladgarol, mor swynol yw si, Ei nentydd, afonydd, i mi. Os treisiodd y gelyn fy ngwlad dan ei droed, Mae hen iaith y Cymry mor fyw ag erioed, Ni luddiwyd yr awen gan erchyll law brad, Na thelyn berseiniol fy ngwlad.
