The Mario Party DS Minigames page has been added starting with 32 4 player minigames, complete with screens. Enjoy.
There are some errors in some of the pages like the Mario Party 8 Minigames page that I am currently trying to fix, so it may be hard to follow.
Besides that the forum is a little empty and new members are welcome. 🙂 Its free, of course and just a click away.
