# Note: Borderlinez's notes:
#  - For easy master ninja rank on missions these codes are not for Ninja trials
#  - Infinite karma gives a ninja dog rank so no use hacking that code, and if you mess with the combo multiplier you will get a ninja dog rank as well .
#  - Mission clear time at 1.13 and the other timer when doing combos is stopped so you will get all your combo bonuses ! 10000
#  - The Jewel of the Spirit Smith crystal can be used to upgrade any weapon without going to muramasa if you just want to upgrade yourself playing the game normally
