IIRC, they rendered the movie twice back in the day, once for the cinemas, and a 2nd time in 4:3, re-framing every scene, for the VHS release.
The VHS cut is how I remember it.

I'll take yumekawaii ultra-femme yuri instead, but I'm cool with the rest uwu

They wouldn't localise them at all because they're all female.
They'd probably replace them with Sonic, Kirby or Yoshis...
Scrap that, not Sonic because they'd never show up on a Mega Drive game.

How many 80s TV anime really have an enduring legacy?
Dragon Ball, Urusei Yatsura...

The 90s had A LOT more cultural icons, Sailor Moon, Ranma, Cardcaptor Sakura, Yu Yu Hakusho, Evangelion, Pokemon, Digimon, One Piece (barely), Lain, Cowboy Bebop, Detective Conan...

The golden age of OVAs maybe, TV anime was a whole other kettle of fish...

As for the 2010s and current cartoons, frankly, I'm not sure I'm even qualified to judge, I wasn't a kid anymore after the 2000s, and cartoons just don't hit the same when you've grown up...

I just installed it and it just works lol

Glad to oblige!
I made Akumanor Gaiden DX for the GBC:
michirin.itch.io/akumanor-gai...

It's short, but it's free, and I'm fairly proud of it! Feel free to include in any way you see fit!

Games like GGXX, Asuka 120%, Stepmania and USC make my list like, Every Year xD

D4DJ and Bandori would have made it too if my phone screen still worked...
