Yes there is, on assisted (aka easy) difficulty, but why i'm asking this is because assisted mode is too easy, lol, because the enemies are also weak as piss too. Standard mode is perfect in every way... except for trying to aim which (for me atleast) is so frustrating (because remember in survival horror games you have to make every bullet count) that it just about makes me throw the controller at the screen!! I'm guessing you haven't played the Resident Evil 2 remake because the "Turn on Auto Aim" selection does actually appear in standard difficulty... it's just grayed-out so you can't do anything with it.
As for the memory editor stuff you mentioned (and all the stuff you mentioned too Necron, thanks for your reply)... no idea how to do that whatsoever. Any chance you could explain to me what to do like you were explaining to a 5 year old... or could i just send you my install folder via google drive and you do it and send it back to me, either of you?
Sharing the install folder would be sharing copyrighted files which isn't allowed on this forum, but I think I can explain.
What Necron said was the same thing I meant
There's a tool called "Cheat Engine". You run that software along with the game. Then you alt-tab to that software from the game and perform a search for memory addresses matching certain values.
It's basically like this:
If you go to the options and turn off auto aim on easy. Go to Cheat Engine and create a New Search, and search for the value 0 (most likely value for "off").
then, go to the game, and turn on auto aim. Go back to Cheat Engine and filter the search with the value 1 (a likely value for "on").
and then you do that, on and off, on and off, to filter out any other memory addresses that might have matched the first time around.
If you are lucky There will only be one address left. And then you can lock or change the value of that address to "1" which would be "auto aim on", even if you play on another difficulty level.
This wasn't really a good explanation (like you're 5 years old), since I'm short on time at the moment, and haven't used the tool in a very long time. But that's the general idea.
I'm sure you can find some tutorials on youtube that will explain it in a more simple way
Or, you might want to search for "trainers" as they're called. They can have all kind of cheats you can toggle on or off, like invincibility or infinite ammo, and maybe auto-aim if you are lucky
Good luck!
