At the moment you'll have to suffer through the lack of sound on this collection of games, but messing with them yourself in your own software environment is not out of the question. The IA collection is optimized for their own super-simple environment so that users can enjoy these ultra-tiny games as quickly as possible.
The current collection consists of games from the Atari 2600, the Atari 7800 ProSystem, the original ColecoVision, the Magnavox Odyssey2 - aka the Philips Videopac G7000, and the Astrocade. Users will be able to browse through each system or by subject or keyword.
Just this week a new wave of games has made this vintage collection burst at the seams, with a load of Atari 2600 games coming up fully prepared to be played instantly. Each game works as a download - if you're logged in - or as an in-browser emulation.
