Hello. Please check the result of your code when generating several values, for example, on seed 2147483645. The error is on line 30. In some cases, the execution of this fragment causes an int variable overflow, which does not happen in Python. It should look something like this:
self.SeedArray[i] = c_int(self.SeedArray[i] - self.SeedArray[1 + (i + 30) % 55]).value

This should fix the issue.
