lol, I've junkied it hard just then.
There are 24 unique minigames, and per usual Rhythm Heaven style, "Level 2" versions have arrived. Some of these minigames are hard as crap... or it's just me, but it took a while to pass them
(didn't use cafe lol)
There are
only 8 2-player simultaneous minigames (that uses the existing minigames - as per the ads) to get, and there's 2-player mode toys!
And the very special addition is the return of FOUR Rhythm Tengoku (GBA) minigames taken from the GBA version to be unlocked
(they'll need some pro Gold medalling though, the first one is at 35 medals FFFFFFFFFFFFFFF)
...and that's my 3 hours of junking
Only got 18x 1P medals, got all of 2P mode medals, and up to the 7th set.
ediT: Also, yeah about the missing text, that's happened to me too. Methinks it's the anti-piracy protection, but I used neogamma as a backup loader instead of the disc channel, and it worked fine... so yeah must be.
