Hi Rainbowman. It has been quite a while since we've last conversed. Anyways, to answer your question about HP and SP in Unlimited Adventure, you are correct that the maximum HP is 2000, but I am really not sure about the maximum SP. The HP stat tends to grow more quickly than SP in this game, and so it takes longer to max out SP. Just to let you know, I don't have this game and I haven't played it either, but I looked up this game on gamefaqs for you and the person who made the FAQ believes that the maximum SP would also be 2000. I guess you'll have to keep on playing this game and leveling up your characters to find out for sure. Sorry that I can't be of any more help.
By the way, when are we going to have some online matches in Super Smash Bros Brawl? I'm still waiting for your answer.
Also, you need to post/visit more often at BOFC forums.
