Does anyone understand how to save on either of these games? I would like to save a game in Pokemon Trading Card Game as I will never beat it in one day. Also, for Legend of Zelda for GB, how do you find the key in the mysterious forest? If you know the answers, a message to me would work well. Thanks!

Your answer is in the Retro Game Room board at https://www.vizzed.com/vizzedboard/thread.php?id=5039
Assuming you are talking about saving in the online games we have here.

Do you mean the Tail Key in Mysterious Forest?

1st - Get Toadstool (Mysterious Forest)
Enter the Mysterious Forest. Go north twice, then east twice and enter the small cave. After exiting from the other side, get the Toadstool lying on the ground.
2nd - Get Magic Powder (Witch's Hut)
Go back through the cave. Go north twice, then east twice out of the forest. Go south twice and east once to get to the witch's hut. Give the witch inside the Toadstool, and she will make you Magic Powder.
3rd - Get Tail Key (Mysterious Forest)
Go back west, north twice, then west into the forest again. Go west once,
south twice, west once, then north once. Use Magic Powder on the racoon to
get rid of him, then go north and get the Tail Key from the chest.

That what you were after?

Thank you very much DarkHyren
