I’ll just re-post the PR that was sent out as it explains how to go about along with the changes made:

This is the same software that was running at IAAPA that they were unofficially calling “The Definitive Version” of the game with corrected/improved handling and some other changes. If you own Sega’s new Daytona Championship USA then today the company wants you to know that you can get a free software update for the cabinet right now. Speaking of that, V1.00 for Stern’s Star Wars pinball was released a few days ago but on to the subject of the post here. It seems to be very inconsistent as to what to expect in this regard – excepting pinball where it’s long been a direct download from the website to a USB stick. For a time, some manufacturers offered the updates direct from their website (or at least a way to download the update) but then some removed that ability. It wasn’t too long ago that most were handled by a CD or DVD that your distributor might send your way, although most of the time you had to know about it and request it.

Arcades and software updates have changed a bit over the years.
