Hack: Pixie Dialogue Skip Patch
Hack: Save Support
  • compatible with the North American version only.
  • does not apply to the Japan ROM but you can use the secret language-swap button code built into the original game (!). Hold L Trigger, R Trigger and Left D-Pad Left then press Start on the title screen; this will switch languages and save the new setting to SRAM
  • adds ability to enable/disable the debug mode. Hold Select while booting the game; this setting is also saved to SRAM. The title screen shows “DEBUG” in the bottom right when enabled
  • enables the Japan-only sound test and fixes the Japanese text to display correctly
  • separately saves progress for all “three” characters from the Select Player screen and/or by entering passwords, i.e. passwords will replace your save games
  • saves the difficulty setting (normal/”for super players”), with separate save slots for normal and super difficulties
  • adds secret character to the Select Player screen. Hold L Trigger + R Trigger while cycling through characters
  • erase individual character saves by pressing Left D-Pad Down four times in a row while they are highlighted on the Select Player screen. There are warning sounds

This patch re-enables two debug cheats for a level select and invincibility which normally couldn’t be accessed, because the programmers deactivated them for the final version of the game.
