Yes, but you need two things – you need the box art, and you need a direct game link. These usually have a prefix of .gba, .nes, .gb, etc., and you won’t get them from services such as MEGA, Google Drive, or MediaFire. The recommended services are Dropbox or your server – we don’t provide official support for anything other than Dropbox or standard file or web servers. When you have the required ROM, open Eclipse and tap on +. Add the art and the link and add it to Eclipse – it should run.
