Well i saw the one LorVolk had posted but it did not have much info in how to use this System,even though i had already written one for my own site long ago,i might as well share it here as it has steps in using YVD properly as well as hosting and joining.Hope this is okay.
Step 1: InstallingFirst things first, you need to go to
http://xerocreative.com/index.php?goto=yvd&sub=downloadsNow what you want to download goes as follows:
YVD 9.0 MSI (try this first)
OR
YVD 9.0 ZIP
Once you have YVD installed, it will be in your start menu.Try the 2nd one first as it is much better/
Now to download the images. All Images ZIP should be at the bottom of that download page. Save it in the YVD Images folder that should usually be at C:\Program Files\Yugioh Virtual Dueling\Images.
Unzip the file in there, and you should be good to go with your basic setup.Btw all the images will not be there.only old cards from GX and the Original series will be present.
Step 2: Using your YVDYay! We have YVD running. Now lets learn to use it.
The Deck Editing part should not be too hard, everything is easy to search up. If there is a need to explain this I will... eh I will do it anyways.
1: Click Update Sets on the interface.
2: Search for the cards you want on the search bar.
3: Click on them to put them in your deck/side deck.
4: When finished, click Save Deck and give it a name.
Note: OCG cards are on OCG mode.
Now when we click on Duel, we will be on the main screen.
Simply press Connect, and from the drop-down Menu, select either of the Server Duel options. You will be asked to create an account, and it is as easy as entering it right there on the pop up.
If you chose Server Duel: Host, your opponent chooses Client, and vice versa. Remember to write your opponents username in the space provided.
If you are able to host IP on KCVDS, the same applies here. Click Listen instead of connect. Your opponent will select Normal Duel: I am connecting to my opponent. from the drop-down menu and put in your IP address.
Some good shortcuts to learn while first getting used to the game are:
Ctrl+D Draw
Ctrl+S Shuffle
Ctrl+K Look at Deck
Ctrl+R Roll Die
Ctrl+G Look at Graveyard
The /add and /sub functions work the same as they did in KCVDS, so no worries there.
I think it only takes about one duel to feel comfy with it, and I will certainly be there for anyone who wants to try it out, or have any questions..
