This is just next-level preservation, dude, keep going! Oh and add Game & Watch Collection 2 and maybe if it's possible add the DSiWare versions of some G&W games.
The games that were rereleased are: Ball, Chef, Donkey Kong Jr., Flagman, Helmet, Judge, Manhole, Mario's Cement Factory and Vermin. Sorry if that's too much for you 馃槄
