The April line-up for the Japanese Virtual Console service, as revealed via Nintendo's Virtual Console page: 

• Darius Twin (Taito, Super Famicom, 800 WiiPoints)
• Pilotwings (Nintendo, Super Famicom, 800)
• Fatal Fury 3 (D4, Neo Geo, 900)
• Waku Waku 7 (D4, Neo Geo, 900)
• Mr. Do (Hamster, Arcade, 800)

There will be additions to follow, and none of the April games have final dates. 

The 30th of March will see the release of both Metal Gear 2: Solid Snake and "Gofer no Yabo Episode II" (known in Europe as Nemesis 3). Both KonamiMSX titles are priced 800 WiiPoints. 

I obviously don't have a Wii, but its nice to hear people will get to enjoy Waku Waku 7. I didn't realise it had Neo Geo support. Just out of interest, will it include online play? 
 
  

No virtual console game has online play, it provides games in their original forms. All these Neo Geo games are arcade perfect though, so this version will feature load times significantly shorter than seen on the Saturn version.
