This seems to have crept out without much fanfare. Collection of Rocket Knight Adventures, Sparkster (Mega Drive) and Sparkster (SNES) with extra bits.
I remember playing the Megadrive and SNES games, I'm sure I still own the cheaper Megadrive one, but the other one goes for about £100 they have a copy in my local CEX.
Thanks s will be a good way for lots of people to enjoy the games.
