So i'm new to the whole reverse engineering thing with only experience in C#. So I wanted to try and change the framerate of applications (eg. this unity game) at an assembly level on iOS ( I have an 120hz iPad pro so I find it really important.) Therefore to learn how this was done I decrypted the binary of my very own app on the app store and then compared it with the C++ code that is created when unity exports to Xcode.
Note the highlighted area and the value of 120 (the framerate). This is in C++. But now in assembly note how the value is simply "System.Int32" Soo what happened to it? Maybe it's something to do with the /hidden argument/ in the C++ code? but for other apps I obviously won't have access to that. I'm still new to this and i've been trying to learn the basics of assembly. I'm just baffled as to what I should do and how the value can be changed? If someone could explain how to do so that would be great. If not a helpful pointer as to what I should learn and do next to solve this problem, maybe links to articles would be also helpful. Thanks in advance.
