I am talking about a normal gameplay I did on console over a decade ago. The predominant method is method 2, just like on emulator.
When are methods H-1, 2 and H4 used? I only tested RSE and this is what I know, I am unsure about FRLG:
Method 1: Legends and wilds (sweet scent and walking, no idea about rock smash and fishing)
Method H1: Never? Maybe having a synch lead will trigger it?
Method 2: Is this a thing? Maybe only walking?
Method H2: Sweet scent, fishing, rock smash. No synch required.
Method 3/H3: Not even reported on the rng reporter, is this a legend?
Method 4: Legends (rare), wilds (walking at least)
Method H4: Maybe having a synch lead will trigger it? After abusing the sav to shiny a method 4 spread, I can't seem being able to shiny that spread as method h4 even with a shynch.
