Just something that crossed my mind. since I primarily play on Emu now cause I don't have a PS3 on hand to play it

Does the skip only work on PS3? (and maybe native hardware?)

The input is just running left after the jump. But on Emulator, I get stuck in the wall. So I think the load time is slightly different and the wall is loading before I make it across so I softlock. It might also be the emulator I use (Retroarch -> Duckstation core)

It doesn't change anything else from my experience, I haven't noticed any other differences, but just this very small time save. Maybe 5 seconds at worst and a bit of stamina loss. You can slightly proceed down the mud path instead. Getting a small headstart down the mudpath also seems to prevent the enemy from spawning as well. (But if you run too far you do risk softlocking as well)
