This project is deprecated years ago. I just open source this project.
YES, I was nimo1993 and used to be in yoyo-do.com forum years ago. That's it!
You may not know that I also have developed another unpublished version and many studios in China used it to make profit on it. (Years ago, again).
However I cannot find the project files, so the only thing I can do is to publish this one. I am sorry that the code is very ugly. Since this is just my childhood memory, forget it :)
