Install guide

Needless to say, you need to install RAI7 before playing.

Recommand system requirement
Here's the recommand system requirement in offical website: CPU Pentium4 2GHｚ以上 HDD 280MBの空き領域 WindowsXp/Vista/7/8が稼動するコンピュータ 解像度1024x768以上、32bit(TureColor)表示可能なグラフィックボード 要DirectX9.0 Here's the translation:
 * CPU needs Intel Pentium 4 2Ghz or above
 * Hardware available needs 280 MB or above
 * Operation system needs Microsoft Windows XP, Vista, 7, and 8.
 * Resolution needs 1024×768 or above. Your color depth also needs 32 bits, or True Color.
 * DirectX 9.0 or above required.

Most modern computers meets requirement. Although Microsoft Windows 10 doesn't list here, it runs perfectly.

Unfortunately, this game is written in Shift-JIS Japanese, which is not compatible with modern UTF-8 encode system. So you will encounter Mojibake if your system locale is not in Japanese. If you don't know how to solve, follow the guide on DLsite.

Non-Microsoft Windows users
This game runs on Microsoft Windows. If your operation system is not Microsoft Windows, its huge challenge for you to run RAI7 because its encode system.

For macOS, Wine can run RAI7 without error exceptions, but Mojibakes can make you almost impossible to read any texts, so you cannot play RAI7 in Wine.

The best way to play RAI7, is using virtual machines. We recommand VirtualBox, which runs Windows XP perfectly.

How to install in legal way
If you want to encourage developer May, or play RAI7 in legal way, you should buy them. In Japan, most indie games are sell on DLsite. RAI7 sells on DLsite, too. In addition, RAI7 also sells on DMM, another popular game platform in Japan. So there're two sites can buy RAI7:
 * DLsite:
 * Main game
 * Power up kit
 * DMM:
 * Main game
 * Power up kit

Recommand to buy both main game and Power up kit.

You will get two  files if you buy both. If you buy these from DLsite, unzip (Main game, you should get a folder called 雷神7製品版 if in correct Japanese) first. Go to main game folder, click, and click the "next" button until the end. You should see files at. Or other destination folder you specify.

Then, unzip (Power up kit, you should get a folder called 雷神7パワーアップキットv3 if in correct Japanese), and go to power up kit folder.

After unzip, click  first. Installation program should automaticity direct your installation folder. Click the "next" button until the end, too. After installation, install  and.

Congratulations, all installation are completed, you can enjoy pure RAI7 now.
