Nintendo has yet to launch its Virtual Console service on the Nintendo Switch, but the company is bringing some classic arcade video games to the console with its new Arcade Archives program, the company announced today during a Nintendo Direct presentation.

These downloadable titles will be Switch ports of arcade games from the 1980s. That’s different from the Virtual Console, which offers ports of NES games.
