LifeLuaJIT is an open-source LuaJIT interpreter developed for the PlayStation Vita (PSVita) , combining ease of use with advanced performance. This project allows developers to run Lua scripts at high speed on the console, leveraging the power of LuaJIT , an optimized version of the Lua language.

With LifeLuaJIT, you can create homebrew, games and applications for PSVita more efficiently, thanks to the flexibility and speed of Lua.

GitHub repository: https://github.com/HarommelRabbid/LifeLua

Main Features

PSVita Integration  – Runs LuaJIT scripts directly on the console.
High Performance  – Thanks to LuaJIT, scripts run faster than with a standard Lua interpreter.
Open-Source  – Licensed under  GPLv3 , ensuring transparency and freedom of modification.
Easy to Use  – Ideal for both beginners and experienced developers.

Documentation

At the moment, the full documentation is under development ( TBA – To Be Announced ). However, you can explore the folder sample in the repository to see practical examples of LifeLuaJIT features.

How to Compile LifeLuaJIT

To compile LifeLuaJIT, you need to use VitaSDK , the official development kit for PSVita.

Basic Steps:

Make sure you have VitaSDK installed and configured.
Clone the repository:git clone https://github.com/HarommelRabbid/LifeLua.git
Go into the project folder and fill in:cd LifeLua make
The generated file .vpk can be installed on PSVita via homebrew loader such as VitaShell .

Examples and Demos

There are several examples in the repository folder samples that demonstrate the capabilities of LifeLuaJIT, including:

Input management (keys, touchscreen)
Graphic rendering (drawing of shapes, images)
System calls

These examples are a great starting point for anyone who wants to experiment with PSVita development using Lua.

License and Warnings

LifeLuaJIT is released under the GPLv3 license . This means that:

It is mandatory to release the source code of any application based on LifeLuaJIT.
Obfuscating or compiling to byte-code without providing the original code is not permitted.

If you intend to use LifeLuaJIT for closed-source projects, you will need to evaluate alternatives compatible with more permissive licenses.

Conclusions

LifeLuaJIT is a promising project for the PSVita homebrew scene, offering a simple and performant way to develop applications in Lua. With LuaJIT support, developers can achieve better performance than standard Lua, opening the way to more complex games and tools.
