New question:
Is there any requirement for a position to be inserted with an erm hook?
Daemon_n told me that it is recommended to put a hook only when there are 5 bytes between opcodes, but from what I see three would also do. Is that correct?
An example is that I put a hook at 0075DE2B for getting one of my creatures to have the same chance of Age with Blood Dragon, but daemon said 0075DE31 is safer. I find no difference between these 2 hooks so far.
