Download LuaPlayer v0.20:
If you have problems with the module loading with 2.00+ loaders, try an older version, like 0.16. See the effect-module and the Game Of Life example how to write your own modules. If you have a PSP with 2.00 firmware, try this EBOOT.PBP Loader, with an older Lua Player included.
This is not an offical Sony development, but based on the homebrew PSPSDK.
For testing, try the Windows version of Lua Player, thanks to InsertWittyName from #pspdev on Freenode now with Freetype TTF and some more functions of the 0.20 version. Some sample applications are bundled for testing, but you'll need the package for 1.0 firmware all sample applications.
Source code of Lua Player itself (you don't need it to write and play Lua Player applications).
Lua Player is a lua script player for the Sony PSP. What this means, is that making your own games for PSP just got that much easier. If you're a regular, non-programming PSP user, take a look at all the games and software available from the galleries.
