Jett Rocket II: The Wrath of Taikai [NA] 2024-05-06

Not much to say about this one; it lets you access all the (non-mirrored) levels, nothing more. You might notice the 'secret' counter for some stages isn't maxed, but there's no actual collectibles to be found there; it just tracks if you found every hidden 1up and the like, nothing important.

Also: don't believe the youtubers. They're REALLY reaching with the 'hidden gem' thing, JRII is just barely mediocre.
