8bitpeoples is an artist collective focusing on the sounds and images that came with early computing and video gaming, specifically chiptunes, or music made either with actual vintage hardware (like using a GameBoy and LSDJ) or with softwareemulators. All(most all) music released on the site is free to download, and many of the artists (such as Bit Shifter and Anamanaguchi) have larger libraries for you to track down. Torrents float around with a mostly-up-to-date collection of the files and somewhat-questionable tagging, or you can simply download each album individually by song or in a zip file.
There's no way to link to individual albums but if you'd like a place to start, hit the discography page and set the view to ALL, then search for these (artist / album + a sample youtube link from one track on the album):
If you'd like to know more about making your own chiptunes, check out the external links at the bottom of the Wikipedia article on the subject. And there's always chiptune.com if you'd like to explore another site.
