Well there were the three Donkey Kong Land games that were for original Game Boy (only the first was different from the respective Country entry; 2 was pretty close to DKC2 and 3 borrowed heavily from DKC3). Those are what you're thinking of BlackPanther.
As for the GBA entries, the third is the only one with a different soundtrack. They all have added features.
- DKC1 GBA has the Scrapbook,
- DKC2 GBA has the Scrapbook as well, but also Funky's Flights missions, Expresso Racing, and a Time Trial mode
- DKC3 GBA has the new soundtrack, as I said, along with a new minigame for Swanky's Sideshow, a minigame at Cranky's, and an entirely new world called Pacifica, which was pretty well done and fit right into place, being upon that island in the northwest.
Of course, the codes changed completely (the only one that stayed the same was MUSIC in DKC3) with the new Cheats menu. I'm still pissed that they removed the MERRY code. That one was hilariously awesome.
As for the video preview... Pretty awesome! The stage that shows during ilp0's track is in Pacifica, btw. And same with the one during Aquatic Transformations, if I'm not mistaken.
Anyways, aside from that, some epic mixage there (like the OC & REMIX during the Crazy Calypso preview and its remix), and the insanity during that damn forest with lightning stage. Who recorded the gameplay footage? Because I can't tell you how many times my entire family (except for my dad, who couldn't play due to Carpal Tunnel Syndrome) died on that damn stage when we first got DKC3, and you just blazed right through it! The music was phenomenal too. Great job, all! Can't wait for the release! A nice variety of genres this time, and I like that. But get some names for those Untitled tracks!
And why does the new album title seem like it was stupid obvious and staring us right in the face the entire time?
