The Retro CDN is the central repository for all files used across all of Retro's projects, including sprites, screenshots, scans, videos and photography. Additionally, the CDN acts as a host of commonly-used copy deployed across multiple projects. We have 30,589 uploaded files .
If you have any questions, first see the FAQ . If this doesn't help, find an active staff member.
Update 20 June 2018 : the 100MB limit for uploading files to Retro CDN has been removed if and only if you use the "Upload large file(s)" link to use multi-part uploads; file limits are realistically 500MB but your mileage may vary. Thanks!
