Cheat MenuEdit

Tsawyer menu

The Game Genie code IEOXAPLL re-enables a cheat menu that was disabled in the final version. To access it using this code, press Up, then Down very quickly at the title screen.

In the menu itself, you can pick which stage to begin at and toggle invincibility by pressing "A" at the option that is labeled as "Normal". "Title" actually leads to the opening cutscene and not back to the title screen.
