CoSMOS Gamehacking Tool

I'm trying to set the level on Zuma's Revenge, but the level number never shows up consistently (changes as I change levels). My goal is to set the level and play that level. I"m not sure how I'd enable power-ups using CoSMOS, so I can't cheat my way to the upper levels that way. I can set the score, but that doesn't really do anything towards advancing to the next level. Anyone know some general tips for setting a level - or if it is even possible?
