The Wonderland Board

I'm not a very good puzzle solver, but I managed to buy all the tokens and 5 gold keys. But now all I need is 26 coins, and all of them are in hard adventures I probably won't solve without a walkthrough.

Can someone help me and provide a pdf. file with walkthroughs for these levels?

Gem Challenge
Button Challenge
Rescue Mission A, C, and D
Power Core

I don't have my POTZ save anymore, but I did record solutions to four of those levels.

Button Challenge
Rescue Mission A
Rescue Mission D

Also, here's a topic for Rescue Mission C, in case it will help: http://pcpuzzle.com/forum/viewtopic.php?t=25260
