In the past 24 hours, I've come across a few troubles with erasing data on a couple of games:

- In Yoshi Touch & Go for the DS, I've found that you can reset the high scores in each mode, but even then, any mode that you unlocked STAYS unlocked. I'm wondering if there's a way to fully erase the records and restore it to 'like new' settings.

- I also can't find any way to erase save games in Super Mario RPG. Again, I'd like to find a way to make it "like new", if at all possible.

Can anyone help me with either of these?
