A wonderful addition has been made to the Internet Archive Software Collection, namely the Internet Arcade collection. There were already many old softwares and games you could download from and/or play in your browser, but you can now play around 900 arcade games in it, thanks to the JSMAME emulator, which is a JavaScript port of the famous M.A.M.E emulator.
The games are available at this page: https://archive.org/details/internetarcade
