Why parse this by hand at all? This file is valid Lua file: let Lua do
the work for you with lua_dofile. You'll have to create Emitter first.
Something like this (in Lua 5.0, but similar code works for Lua 4.0):

 local particle = {Emitter={}}
 local f=assert(loadfile("yourfile"))
 setfenv(f,particle)
 f()
 print(particle.Particles)
 print(particle.Emitter.delay)
 print(particle.Emitter.delayFuzz)

If you don't mind polutting the global space then dofile("yourfile") suffices.
