How to load a custom quest
When you first load up zelda-w.exe, you will come up to a screen similar to this after the title screen.
You can move the little heart around with the arrow keys, you should move it down next to the "Register" option like so.
You can now use the keyboard to type in a name for your save file. I used Demo for this walkthrough.
Now that you have registered your name, the next thing you do is hit the "A" button (By default, it's the left-alt key on the keyboard) and it will bring up something like this.
Now, hit the "A" button again to bring up a popup like this.
You can now see a button that says "Browse" (I circled it for you. ) Click it with your mouse.
Now you see a list of quests you have downloaded and placed in your ZC Directory. You see I have quite a few quests, but that's because I play a lot of quests. I'll use puzzlequest.qst in our demo.
(I circled it for you. ) You can scroll and look for the .qst file you would like to play and then double-click it.
Now you see the previous screen, but it's filled with information. See screenshot.
That means you've loaded a custom quest. Now all you have to do is click "OK" (I circled it for you. ) Then hit the Return/Enter key on your keyboard and start playing!
