Regional Differences

Trigon is the Japan version with a Japan only disclaimer screen. Checkpoints upon death and the Trigon powerup exist in 1p mode.

Lightning Fighters can be three different versions: The US and Asia versions have no checkpoints and no Trigon weapon in 1p mode. Players will spawn with one Lightning Sword (Particle Beam) each life unlike versions with checkpoints which respawn with no bombs in stock. The World version of the game is also called Lightning Fighters but DOES have the Trigon weapon and checkpoints in 1p mode.

The only way to determine which version of Lightning Fighters is being looked at depends on the attract screens:

  • US version will have the "winners don't do drugs" disclaimer.
  • Asia has a "for use in Asia except Japan" disclaimer that looks like Japan version's disclaimer.
  • World has no drugs or region disclaimers whatsoever.

2p mode is identical across all versions with two players. More specifically, LF US and Asia are always in 2p mode even with just 1 ship.
