yep. ps2 is faster than arcade. xbox is faster than all. imo
I guess I read that xbox was slower on a thread years ago. Ps2 feels fastest to me but no mater, I haven’t really compared them side by side. Just fingers crossed that someone uses the relevant versions of the game and shows us what ‘arcade perfect’ really means.
Yeah I think Xbox anniversary edition runs better on an actual Xbox than on an Xbox 360.
Be cool if someone was gonna do it, to do it right i.e Xbox AE, Xbox AE on 360, PS2, Arcade, PS3 OE and Xbox 360 OE.
Although I agree the Xbox AE test isn’t as important.
SOMEONE PLEASE DO THIS! 
Emu is fast too. Maybe PS2 speedish.
Play on a cps3 cab for a few hours then play any other version and it’ll feel strange as fuck. I was trying to show my friend a few things in 3S on the xbox AE version and I couldn’t do ex mgb, jab mgb, jab mgb, etc. at all until I realized and sped up my timing considerably. Then it worked. Felt really strange.
