Yeah, honestly I expected proper ports at the very least. Emulation is just lazy, may as well play them on my PC. Although it's nice to have them portable.
@The Real Jdbye Well, I more so meant 64 DS > 64 Shindou, and that I don't have a high opinion of Sunshine or Galaxy whatsoever due to their focus on linearity and introduction of frustrating Shines/Stars (and Galaxy's unwarranted HP nerf), but sure. That too, I suppose.
Well, when you enter Sirena Beach (or whatever), you're railroaded into doing Mission 1 -> Mission 2 -> Mission 3...all the way to Mission 7, which has Shadow Mario and is required to unlock Corona Mountain (Mission 8's optional). Aside from using glitches, you can't select Mission 1 and go off and complete Mission 4, as far as I know, when this is entirely possible in 64 (DS).
