Run_js_game_further_preparation

[zhaofeng-shu33]

The ReadMe.md file is not updated timely to show the recent commit change.
I do not know how to prepare the mp3 files, so the user should commit out all the music.play fuction to
let the js code run.
The other file is desc.dat, which should be prepared by decompress data.mkf and rename the third block to this file name, is it true or false?
