how do u unlock it?

You must beat everyone in exhibition mode under pro difficulty, Ace difficulty is only for exhibition mode

wut about technical difficulty?

Just win the peach's tournament on any difficulty in either doubles or singles, and it will be unlocked for power tour mode.

oh yeah, duh, i unlocked it on my deleted file

Oh yeah, lol, i forgot about that, I have a question for you, even though the file is deleted, do you still have that difficulty unlocked?

Nope, i wish though

Okay, because I just wanted to know if I ever decided to delete my game data in order to see how fast I could beat it again.

You did know that you can look in the cheats to find this?

Yes, I submitted it a few days ago and its on there right now.

Yes, I have just seen them. That ace difficutly takes forever to unlock. I still haven't yet.

When you beat someone in exhibition under the Ace difficulty, go to the stats and got to the exhibition stats. There is a little multi-colored star under there name.

Wow, I haven't even done exhibition mode yet. I think that I will try it out in a few minutes. I am pretty sure though it is just like a friendly match or something like that.

Wow, Ace sounds hard to unlock!! I'me going to try, does this mean even the star characters? And does it count if we do it in doubles??

It doesn't matter if they are on star or not, and it has to be in singles in order for it to work.
