From “SimCity” to “The Last Ninja,” video games developed for the early home computer C64 remain classics today. A digital library based in San Francisco is now offering them for free online. We can hear GenXer peeps getting twitchy with excitement.

The Internet Archive at archive.org collects anything digital – software, music, books, websites, films – to make it freely available and preserve it for posterity. C64 software is the newest addition, including nearly 9,000 games like “Gauntlet,” “Castle Wolfenstein” and “Crazy Cars.”

They join a collection of vintage games that also includes arcade games, MS-DOS and PC classics, collections for old video game consoles and Amiga games.

They can be played on a PC using a so-called emulator. But a download is not always necessary, as the games will often load directly in your browser.
