I heard a rumour that the one who worked on the DS port for Sega is the same guy who made a homebrew Genesis emulator for the DS. His real name appears to be in the credits.
Sega´s lazyness once more shows itself. =w=
That's not too surprising. They bought the Java version of his emulator several months ago and are now using it for playsega.com
I just picked this game up today! It has some slowdown, but it is way less noticable than in Sonic Genesis (except for Sonic 1 which i would swear is an exact port of that port)! Sonic 3 & Knuckles has a few instances hear and there before bosses! It's definately not perfect, but it will sufice if you just have to play the old Sonic games portableized! The oddest thing about the package is that the menu lists Sonic 3& and Knuckles as "Knuckles in Sonic 3"! Oh, and the missing options menu in Sonic 2 bout made me cry! (I love sound tests!)
Would it be too much to ask for a compliation of all the Genesis Sonic games (The good ones that is) and include the option to play with Knux and Tails in Sonic 1?
