元旦準備買NDS，順帶關注了下PSP，其實是想，或許買PSP也不錯~

PSP很像一個平臺，提供了很多東西，譬如官方的PS模擬器~在上面編程也是個不錯的想法。

國外的一個網站提供了很多信息，PS2Dev Network (http://www.ps2dev.org)，有教程http://ps2dev.org/psp/Tutorials，現在由于不久前的地震，基本無法登陸那個網站。更多的信息在http://wiki.ps2dev.org/。

要想進行PSP編程，需要學習C或C++。在windows下，需要安裝Cygwin http://www.cygwin.com/, 這其實是個模擬linux的環境。在Mac OS X或Linux下需要編譯PSPSDK和PSP 工具。這些東西都可以在http://ps2dev.org/psp/Projects找到。

你也可以使用HTML, CSS和JavaScript編寫程序在PSP的瀏覽器上運行。關于這方面的信息，網上已經很多了，這里給一個例子。

你可以將其與Perl腳本語言結合，編寫功能更為強大的程序。

(聲明：以上大部分翻譯自《PSP Hacks》的Hack 47. Develop for the PSP)

不知道PSP是否支持Python這種腳本語言~大學里看過Python的書~

Lua是linux下的一種編程語言，那另一中語言Ruby是否也可以呢？
