<p>Lua is built into FCEUX as of 2.1.2, and luapack DLL files are no longer needed in this and later versions.</p>
<p><br></p>
<p>To run lua scripts in older versions of FCEUX, you will need the lua pack which can be found <a class=rvts12 href="http://fceux.com/luapack">here</a>. The .dll files must be unzipped in the same folder as fceux.exe.</p>

<p><span class=rvts10>Core Lua Documentation</span></p>
<p><span class=rvts11><br></span></p>
<p>If you have never programmed, you will probably want to start by learning the basic of Lua, which is too broad for the scope of this help file.&nbsp; Try searching on the Internet for "Lua tutorial".&nbsp; As of this writing, it's official homepage is <a class=rvts12 href="http://www.lua.org/">http://www.lua.org/</a></p>
<p><br></p>
<p>If you are familiar with any programming language you will probably not have too much difficulty adjusting to the syntax and structure of Lua.&nbsp; You will probably also find useful information on the Internet.</p>
<p><span class=rvts10><br></span></p>
<p><span class=rvts10>GUI Frontend</span></p>
<p><br></p>
<p>To use a Lua script, you need to create one in a text editor.&nbsp; The name of the file created should end in .lua to indicate that it is a Lua script.</p>
<p><br></p>
<p>To run a Lua script, choose "Run Lua Script" ***from where***&nbsp; In the dialog that pops up, click "Browse" and find the file you wish to run.&nbsp; This will insert the path of this file into the dialog.&nbsp; You can then click on "Run" to run the script or "Cancel" to return to FCEUX without running the script.</p>
<p><br></p>
<p>To end a Lua script, choose "Stop Lua Script" ***from where***.</p>
<p><br></p>
<p><span class=rvts10>FCEUX Lua Basics</span></p>
<p><br></p>
<p>Your script will be constructed according to the rules of Lua, but you will use FCEUX-specific functions to interact with the emulator.&nbsp; For example, one of the most often-used functions is emu.frameadvance() which will tell the emulator to advance exactly one frame, which is the basic unit of time on an NES.</p>
<p><br></p>
<p>In general, your script will probably want to be run until you tell it to stop, so it will look something like this:</p>
<p><br></p>
<p>emu.speedmode("normal") -- Set the speed of the emulator</p>
<p><br></p>
<p>-- Declare and set variables or functions if needed</p>
<p><br></p>
<p>while true do</p>
<p>&nbsp;&nbsp; -- Execute instructions for FCEUX</p>
<p>&nbsp;&nbsp; emu.frameadvance() -- This essentially tells FCEUX to keep running</p>
<p>end</p>
<p><br></p>
<p>The way instructions are sent to FCEUX is through a set of specially defined functions (and variables) which are called an API, the specification of which follows.</p>
