X-treme card

I've searched this forum, but see no one with an X-treme card.
I even used the search engine, but found zip...I wonder if anyone has this card. It would be nice to exchange tips and tricks, maybe???You might say: go to the X-treme forum... Well I did, but on that forum it is forbidden to talk about roms and so on...So when I have a problem, it's hard to find support.
That's why I'm looking here...GreetzzzDolphin
