请各位大牛速度进来帮忙，看看怎么修改这个MP3源代码

[lvluluzhu]

本人在网上下载了一个基于A8的mp3播放器代码，准备修改成毕业设计，但是经过多天的奋斗，还是修改不出来吖，悲催吖，学校地答辩就快到了，着急中。。。。

有木有那位大侠可以帮帮忙的，感激不尽吖。改成基于s3c2440或s3c6410都行吖，源代码里面不包含main.h和s5pv210-gpio.h两个头文件的，这是我自己添加进去的，我自己也不知道有木有对。源代码看附件。改好跟帖或发邮箱：[e-mail]，在这里，先谢谢各位的帮忙。


还有几个源代码发布不出来，只能连着回复3次，我等迟点发，或你联系我的邮箱：[e-mail]
