We've already got threads on how to use back up saves, which is the only reference people are going to get.
Check out this PSA, on discussion of how to use Cheat Engines. We delete tutorials threads for this kind of stuff (with the notable exception of Etesian's breeding guide), and the chances of us making a thread on fixes is unlikely.
If people post in bug reporting with Cheat Engine files, I'll direct them to the back up saves thread, but that's all they're getting.
In terms of adding pokemon for a mono or duo type run, that isn't considered cheating here, we even have a thread for it. Challenge runs are generally exempt from the rules on adding pokemon, so there are no worries there.
