I'll search if I find any tg dumps..
About the megadrive games. Are they really being run with 'classic' emulation? Aren't the megadrive games run more like some kind of remakes? No one would be happier if it would be possible to inject megadrive games. But I can't believe it will ever happen.
EDIT: TG16 VC are:
Gradius
The Kung Fu
Devil Crush
R-Type
All of them are from Konami. But I cant find any dumps from the two biggest 3ds sites and are not listed on 3ds.essh.co. Ill put up a request and see what happens
