高速iDuel卡图下载工具下载-软件下载

iDuel自带的卡图下载工具慢到不能忍...于是自己写了个
只有一个功能 就是下载/更新卡图
下载速度应该能占满带宽

需要放到 OCG联网决斗模拟软件(iDuel) 目录下。

实现代码：

exit
end

cards = IO.readlines('data/allcards.dll').size / 2

config = IniFile.new IO.read('data/config.ini', mode: 'rb:BOM|UTF-16LE:UTF-8')
path = config['Config'] && config['Config']['CardImagePath']
end

if !path or !File.directory? path

path = Win32::Registry::HKEY_CURRENT_USER.open('Software\OCGSOFT\Cards') { |reg| reg['Path'] } rescue ''
path.force_encoding(Encoding::GBK).encode!(Encoding::UTF_8)
end
