To activate cheat codes you first have defeat the game.
If you have NOT defeated the game, you will have to edit a file using a Hex editor. (ugh). We take NO responsibility if you screw things up while trying to hex edit the game file so make backups!!
- Hex Editing instructions:
-
Before proceeding, make a backup copy of 'persist.dat' - without it your game will not function and you can really screw things up if you don't do this properly.
Open 'persist.dat' with your favorite hex editor. It should be located in the directory where you installed Oni (c:\program files\oni by default).
Go to hexadecimal Offset 44 - the value should either be '02' or '06'.
Change this value to '07'. Save and close the file.
Now you're good to go!
Once you have unlocked the cheats, press "
F1" during gameplay to open up the personal data assistant. Type in the following codes to activate the cheat. If entered correctly, you will see text appear in the bottom window of the PDA.

Notes:
** The shapeshifter code lets you play the game using another character such as a striker, Muro, Barabas, or the enemies. When you play with other characters you get to use their moves. This is a leftover of the multiplayer features that Oni was
supposed to ship with, before they canned multiplayer altogether.
