After you have all three of the above, we can get started.

1.)Extract Particle_Editor_with_Mungs.exe.
2.)In the extracted files, you'll find the Munged folder, ParticleEditor_BFII, and the ReadMe.
3.)Move the Munged folder and ParticleEditor_BFII to LucasArts\Star Wars Battlefront II\GameData\DATA\_LVL_PC.
4.)Run ParticleEditor_BFII. An error message would pop up "Could not read common.lvl". Ignore it.
