Does using the 5-node "cheat" in Dead Space affect gaining trophies?

I discovered the button combination on a site when I was researching Unitolgy's background and stuff like that. I'm currently going for the "One Gun" trophy and the "Epic Tier 3 Engineer" trophy simutaneously. It's actually going pretty smoothly, but I put this code in just to see if it worked, and I want to know if I need to re-do the entire game now. I do NOT use any other cheats, nor have I attempted to. So it's just a matter if THAT one affects me gaining those two trophies at the end. Thanks!

I used all the cheats and none of them disabled trophies for me.

Thanks a bunch man!
