I think midair unmorph jump is slower make with PAL-versio.
I think norfair supermissile room shortcuts not working PAL-versio but i not sure this. (Watch: segment 5 -ajbolt89 100% hard video) he jump and put bomb upper roof and roof explode.
I practice this trick long time, but i not find possible way make that trick. i`m skillful player with metroid zero mission, but i`m pretty sure this trick is not possible make PAL versio, i think europa versio move little bit more slower than Ntca versio.
Nope, it's possible cause I've got it on video with German language on my run... what you need to do is jump, morph and lay one bomb in the air above the ground, so that it propels you upward but doesn't touch the ground beneath you. Then using that you go toward the wall and bomb higher up. It requires near pixel-perfect accuracy to just jump at it and morph, and lay a bomb high enough. It's not worth how hard it is.
