Lua for the PlayStation Portable is interpreted with Lua Player. Lua Player is a homebrew application which can run lua scripts and display them on the Sony PSP through graphical bindings. The current version is 0.20, however v0.17DK2 and Lua Player Mod, which are unofficial versions are still used by users on PSP Firmware version 2.00+. Most versions of the application can be downloaded from the LuaPlayer.org website. Lua Player can only run the source code of Lua scripts, and can not compile them into standalone software applications.
Programming[edit]
The programming language for Lua Player is almost identical to that of Lua programming language. Below is an example of a basic hello world program.
green = Color.new(0, 255, 0)
while true do
screen:clear()
screen:print(200,100, "Hello World!", green)
screen.flip()
end
Authors[edit]
Lua Player is an open source project, and was originally maintained by Frank Buß (Shine) and Joachim Bengtsson (Nevyn), before being passed on to David Perry (InsertWittyName).

Libraries[edit]
To load a library in Lua Player, one would type dofile("libname.lua") assuming the library's file name was "libname"
Some common libraries are:
- netlib which allows you to make a game online capable, send emails and send text messages. This library was written by Youresam.
- BMPlib which allows you to load bitmap images into Lua. This was written by Youresam.
- wavlib which allows you to easily integrate visual for audio data in a program made by youresam
- Animation Lib 4 which allows you to easily create animations in Lua. This was written by Grimfate126.
Lowser[edit]
Lowser is the official PSP based browser for lua scripts. It is written in Lua Language itself however is quite basic. Lowser is what is set to autoload when LuaPlayer is started, however this can be changed.
- LuaOS created by Youresam is a shell for the PSP designed to replace Lowser. This has now been replaced (by him) with:
- LuaOS[hell]2 Work had stopped on this, with just the mainframe (LuaX) in a usable state.
- Ys-OS This is a shell created by Yossi-Starz that was not designed to replace Lowser as it is not currently full speed, and is too "RAM hungry" for everyday use.
- LuaMainframe created by Alex Glynn (Glynnder) is a modification of the Lowser script, adding features but limiting speed somewhat. This has now been replaced (by him) with:
- interfaceLua A redesigned and optimised version of LuaMainframe. Work has stopped on it.
