Hey, so, I'm not EXTREMELY new to game hacking. I've done simple value changes, and only recently figured out (somewhat) how to use pointers to find values.
My problem is; In Hades, there's a gun-type weapon. The ammo address changes EVERY time you go to another chamber. Yes, the address.
Changing and freezing the value is no problem, but having to find the new address every single time I enter a chamber, which last not even a few minutes, is infuriating.
Thanks for reading this, at least.

Find a pointer to that address. You may not find a static address; that's fine. Just keep going up until you find a path that remains valid between levels. The pointer scanner may help (maybe disable "Only find paths with a static address"; if you do, also reduce max level to 2-3).

If you want a static address but can't find one, use code injection to automatically get the address itself or a pointer that remains valid between levels. Look up "injection copy" for more information. If you just want infinite ammo, you might not need to copy anything.

The best method that I can think of is to locate the opcode writing to those addresses. But I know from my own experience with Hades and Unity that even if you do find the opcode, there are thousands of other addresses that it writes to.
