In this tutorial I will explain to you how the DGCA file format works, and show you where to download the latest version.
The reason why I put this up is because a few characters made by the Japanese are in the DGCA format like American Idiot final version.
So let's start.
1. Go to this site: emit.jp.
2. Click on --What you'll click on-->DGCA<--What you'll click on-- version 1.10
3. Click on: --What you'll click on-->dgca_v110.exe<--What you'll click on--(自己展開形式 1,271,984byte)最新
4. Click save and open the program. It is all in Japanese. Click on the button that has the N in parentheses all the way through the installation since it doesn't matter. Now you have the program.
Now, let's download a character using this DGCA program!
Let's start by dowloading lucky_clover (American Idiot Final version)

Open the .dgc file with DGCA.
Here's what the latest version of DGCA says in the window (It's in English, hooray!):
