MAME LUA DefaultLG Game Files

You will need the LUA scripts to make the DefaultLG game files work. The LUA scripts use the MAME debug port to read the memory of the game, and then output the data. These are separated game files, because the lua scripts are needed.

Beast Busters 2
Carnevil - Life/Damage don't work, unless you have my modified version of the script.
Crypt Killer - Only P1 & P2 work, unless you have my modified script to make P3 work.
Duck Hunt
Invasion: The Abduction
Judge Dredd - Player 2 stops the output signals, unless you have my version of the script.
