These are update files for use with any Pump it Up Fiesta EX arcade machine that's not yet been fully updated.
These update files aren't hosted in perpetuity and are generally deleted shortly after the game's been removed for purchase, so I'm uploading them here to ensure they're accessible to anyone who needs them.
These updates were released for free for anyone to download, though they're of no use to anyone who doesn't own a legitimate copy of Pump it Up Fiesta EX.
This includes every single update released throughout Fiesta EX's lifespan.
