You know it's not as hard as it looks (but it's not even close to easy
) if your where I am (around 32 sprites, and about 200,000g total). It's actualy very fun doing all this.
What I do is I go here and I tally every sprite I think I can get (that I don't already have), and usualy you have extra sprites in case you can't do one or two. It really makes you want to pick up your DS and start playing again
(but then your DS is almost out of juice
. Yeah I've been there
