I'm no expert on the cheat function by any means, but I was able to figure it out enough to create some cheat codes in order to add rumble support to NES games. An example of how to make infinite health would be something like this: Make a save state, start cheat search, lose health, search for results less than, load save state, search for results equal to before, lose health, and keep repeating until you get it under 10 results. Once you get it under 10 results, choose the option to save them. Then one by one try enabling each one until you have infinite life. Follow the same type of searching for infinite lives, time, continues, etc. At XER, we have a cheat/save file section in the hope that people would upload some of their configs (as many people talk about having them) but not many seem to want to upload them (wish they would though).
