If that were the case, then sure, otherwise it shouldn't be in the category it currently is in.
ferraroso owns it, so maybe he could share some information and perhaps confirm if it works with the Dreamcast or not - possibly even share an image of the back to see if the Dreamcast is mentioned there seeing as the only image we have to go by is the front.
EDIT: Although I just checked and it seems he doesn't have the original packaging...
