Let me point you to the right directions first. Thin we will l get to the ISO. http://www.xpgamesaves.com/forum/4-introductions/
I've looked into the bigger files, can't remember their name since I'm not near my computer but they're like 400-600mb, and I've seen things such as god mode toggle and a developer mask along with invulnerable = false. tried switching that to true and change the value of health and armor but didnt work. the files are random numbers and there's a lot. I'm sure there are other checks in those but that will take a while. and idk how to make .bundle files readable. they're still encrypted/ compressed for the most part so if someone can figure out how to get full access to them then I don't mind taking the time looking through all those files
