Have you tried reaching out to Matt Ownby for an acceptable Star Rider img?
Probably best to reach him via facebook, or discord?, not the old daphne page.
He does have an image that is used for Dexter. Whether or not its applicable to Mame or he is willing to take the time to make it, or share what he has to have converted is up to him. Daphne has been on the update to do list for eons so don’t be shocked if he cannot assist but it does not hurt to ask.
