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 21,834 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!
The migration of commonly-shared files and NEC-related files is ongoing at this time. If you find any files shared between Sonic and Sega Retro, please move; if you find any files that will share between Sega and NEC Retro, please move.
Before uploading any images, be sure to read over the FAQ and upload form. Hopefully, these will help resolve any problems you encounter.
