The default speed for arcade ST is Turbo 1, so isn't that the way the game was meant to be played? Otherwise, reversals and execution in general wouldn't be so flipping hard.
When did people get the bright idea to bring it up a few notches? Well, it was probably the arcade owners that made the decision.
Everyone plays it on the Turbo 1 setting in GGPO, and yet, you have people playing on Turbo 3 in HD:Remix. If arcade perfect ST is so important, then why isn't everyone sticking to its default speed?
