(The term 'DRM' is not generally used in Flash, but we've used it for ease of understanding.) DRM content is a content protection feature applied by Flash developers themselves, which prevents files from being executed on unauthorized websites or using unauthorized methods.
So if you have self-protected content, you may not be able to run Flash on archive sites in some cases. It is possible to bypass this, but depending on the Flash file, it may take time to manually modify the code.
The archive site strives to provide DRM-free content where possible. This may require help from the community.
