Thinking again about it, every PRNG has a state stored somewhere, it can be a list of numbers (like for a MT), or it can be a single number. If there is a list, there is an additional number -the index- that tells the generator which entry it should pull out of the list.
So in theory there should be a variable (the state or the index) that changes every time the generator spits something, and only at that time, meaning you could find it with changed/unchanged scans, freeze it and always get the same results.

(There is also the case where an entry of a list would be modified after being used, there you'd have to find another variable after locking the index)

Hint: for a Mersenne twister, the index varies between 0 and 623, increasing (or decreasing) by 1 at each draw, until it reaches 623 (or 0) where it resets to 0 (or 623)


I already tried all of that with no luck. I am guessing my best bet would be to cheat on something else.
