Two classic games from yesteryear have been rated by the Australian ratings board, possibly indicating a re-release in the near future.

The first is Dug Dug II which originally released in arcades before being ported to the Nintendo Entertainment System. Dig Dug II has actually already seen a re-release on the Wii virtual console, though it's yet to release on the Wii U's digital store.

Then we have the light-gun shooter Hogan's Alley which was recently rated. Hogan's Alley also released originally in arcades and on the NES, though this one hasn't had a virtual console re-release.

However, that may change in the coming weeks or months as it looks likely that both titles will hit the Wii U virtual console sometime in the future.
