Capcom's about a month late to use a classic Mega Man game as a promotional tool for Mega Man 10, but that's okay! Mega Man 4 is now available on the European Virtual Console, and even though it's slightly mis-timed, the end result is that you can buy another Mega Man game right now. Also available on Wii is Ghostfire Games' gladiatorial Punch-Out!! variant, Rage of the Gladiator.
DSiWare's new downloads include a collection of puzzle games (sudoku, kakuro, anagrams, etc.) and the downloadable version of Mr. Driller.
