I finaly got my Netlink to work. I can e-mail savefiles from my Saturn and download files from planetwebÂ´s Game Exchange. But if I tries to e-mail savefiles from Outlook it wonÂ´t work. If I opens the e-mail in Outlook the attachment is there but not if I opens it with Netlink.
The Netlink seems to use a slightly broken version of MIME, which is why simply attaching the saves won't work. I guess you could manually insert the headers (copy them from a Planetweb mail) and then insert the b64-encoded file.
