Zero Wing (Genesis)

A port of Zero Wing that wasn't released to the U.S., and is infamous for its butchered translation of the introduction sequence in the European version.

Test Mode


Pause the game, then hit C, Up, B, Down, A, Left, Right, B, C, C, Right, Left, Right, A, Down and Start to bring up the Test Mode menu, which is similar to Hellfire's.
 * Active: if set to 1, makes you invincible to enemies, auto-destroy some enemies on contact (apparently? TODO), and lets you cross through floors/ceilings/walls unharmed
 * Screen: appears to select which of the possible checkpoint locations to continue from after leaving the menu
 * Stage: select a stage
 * Power: determines the power of your weapons
 * Ending: if nonzero, selects one of the game's endings to view

This menu is present (and functional) in both the Japanese and European versions of the game.
