Brand new here looking for a tutorial on USA region Resident Evil 4 Remake game save 100% complete, all weapons, all trophies, and all content

Hey everyone basically brand new here and no idea how this works. I've already completed RE4 remake on PS5 but looking to figure out how the game saves work (Maybe a tutorial) I basically want to get all the unlockables for infinite ammo, all weapons etc. Not really sure how these save things work or where this can go bad (Deleting my existing game saves etc.) Does anyone have a tutorial for USA region game saves and step by step how to do this? Thanks so much in advance!
