Right now I'm messing with the last stuff I can for Ninja Gaiden Sigma 2. But once I'm done, I might actually go to this game because I'm surprised at some stuff missing. I also thought my signature on this site had the links to the PS3 codes Artemis database, but I guess not even though I know I've posted them here before. It's here either way.

If you're ever up for it, there were a lot of codes for the PS2 version not here. Nobody has made a code to jump in the air or use the special Sparta Sword Devil Trigger whatever from the last battle with Mundus anywhere, nor the level modifier or just unlocking the stuff in the main menu. No codes for having all items, rapid fire grenade launcher or fully charged nightmare gun or anything. There could be codes to easily just auto-complete a chunk of the secret missions or press a button to kill all enemies. Lots of stuff missing that I thought would have already been done by somebody at this point in time 7+ years later. This is the sort of thing I would have assumed GuitarMan would have done by now since he likes messing with Devil May Cry games. You could go for those, but if not, I'm going to likely be on that in a week when I'm done with the last of the stuff to mess with in Ninja Gaiden Sigma 2 since I don't have much left to mess with beyond just getting this code to jump in the air working for all characters, and then I'm done since the only thing I can't get working from a lack of patience is an actual character swap.
I also don't do tools or RTM tools or any of that. We already have a tool that does every game, and that is Netcheat. Going from NetCheat to somebody's RTM tool is like going from having money in your pocket that works everywhere to just a gift card for McDonalds that only works for McDonalds, you've restricted yourself. It's nice for learning how to make one, but that's about it.
