Documentation Build Status

Description

Lua Player Plus Vita is the first lua interpreter made for the Sony PlayStation Vita.

The interpreter currently runs under LuaJIT 2.0.5 with slight additions from Lua 5.2.4 (for example the bit32 lib for bitwise operations). It has also a debug FTP server to correct your errors in runtime.
