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。
ScriptScribbler (http://www.scriptscribbler.com) 這個網站現在提供3篇教程，是由Brad Dwyer寫的。他也可能會增加教程。第一篇(http://www.scriptscribbler.com/psp/tutorials/lesson01.htm) 教你在windows上搭建開發環境。第二篇(http://www.scriptscribbler.com/psp/tutorials/lesson02.htm)教你寫一個簡單的“HelloWorld”程序。第三篇(http://www.scriptscribbler.com/psp/tutorials/lesson03.htm)最有用了，也就是“PSP編程速成”。
如果你不想學C或C++，那你可以用LuaPlayer (http://www.luaplayer.org/)，它也有教程http://www.luaplayer.org/tutorial/index.html教你編程。如果你想學這個，可以到http://forums.ps2dev.org/viewforum.php?f=21多逛逛。使用Lua，你可以在Windows上測試調試，不需要每次修改后都要放到PSP上運行看效果。關于Windows版的LuaPlayer 你可以到http://forums.ps2dev.org/viewtopic.php?p=22332#22332察看更多信息。
這里有一個例子。

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？
