元旦準(zhǔn)備買(mǎi)NDS，順帶關(guān)注了下PSP，其實(shí)是想，或許買(mǎi)PSP也不錯(cuò)~
PSP很像一個(gè)平臺(tái)，提供了很多東西，譬如官方的PS模擬器~在上面編程也是個(gè)不錯(cuò)的想法。
國(guó)外的一個(gè)網(wǎng)站提供了很多信息，PS2Dev Network (http://www.ps2dev.org)，有教程http://ps2dev.org/psp/Tutorials，現(xiàn)在由于不久前的地震，基本無(wú)法登陸那個(gè)網(wǎng)站。更多的信息在http://wiki.ps2dev.org/。
要想進(jìn)行PSP編程，需要學(xué)習(xí)C或C++。在windows下，需要安裝Cygwin http://www.cygwin.com/, 這其實(shí)是個(gè)模擬linux的環(huán)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(gè)網(wǎng)站現(xiàn)在提供3篇教程，是由Brad Dwyer寫(xiě)的。他也可能會(huì)增加教程。第一篇(http://www.scriptscribbler.com/psp/tutorials/lesson01.htm) 教你在windows上搭建開(kāi)發(fā)環(huán)境。第二篇(http://www.scriptscribbler.com/psp/tutorials/lesson02.htm)教你寫(xiě)一個(gè)簡(jiǎn)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(xué)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(xué)這個(gè)，可以到http://forums.ps2dev.org/viewforum.php?f=21多逛逛。使用Lua，你可以在Windows上測(cè)試調(diào)試，不需要每次修改后都要放到PSP上運(yùn)行看效果。關(guān)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(gè)例子。

你也可以使用HTML, CSS和JavaScript編寫(xiě)程序在PSP的瀏覽器上運(yùn)行。關(guān)于這方面的信息，網(wǎng)上已經(jīng)很多了，這里給一個(gè)例子。

你可以將其與Perl腳本語(yǔ)言結(jié)合，編寫(xiě)功能更為強(qiáng)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(yǔ)言~大學(xué)里看過(guò)Python的書(shū)~
Lua是linux下的一種編程語(yǔ)言，那另一中語(yǔ)言Ruby是否也可以呢？
