元旦准备买NDS，顺带关注了下PSP，其实是想，或许买PSP也不错~
PSP很像一个平台，提供了很多东西，譬如官方的PS模拟器~在上面编程也是个不错的想法。
国外的一个网站提供了很多信息，PS2Dev Network (http://www.ps2dev.org)，有教程http://ps2dev.org/psp/Tutorials，现在由于不久前的地震，基本无法登陆那个网站。更多的信息在http://wiki.ps2dev.org/。
要想进行PSP编程，需要学习C或C++。在windows下，需要安装Cygwin http://www.cygwin.com/, 这其实是个模拟linux的环境。在Mac OS X或Linux下需要编译PSPSDK和PSP 工具。这些东西都可以在http://ps2dev.org/psp/Projects找到。

你也可以使用HTML, CSS和JavaScript编写程序在PSP的浏览器上运行。关于这方面的信息，网上已经很多了，这里给一个例子。

你可以将其与Perl脚本语言结合，编写功能更为强大的程序。

不知道PSP是否支持Python这种脚本语言~大学里看过Python的书~
Lua是linux下的一种编程语言，那另一中语言Ruby是否也可以呢？
