Note 1: And these are the side effects of that code. Bowgun aiming is off. Game acts weird if an enemy grabs you. Leon seems to move a bit slower than usual, but he's still faster than the enemies. Everyone else from mercenaries moves at normal speed. Ashley moves slow. You can't reload, you can try but you'll still have the same amount of ammunition. Basically everything except you moves slower (unless you are Leon).

Note 2: I noticed the pistol and TMP and a few other guns had their damage greatly increased so some enemies died in 1 hit, while some guns will have their damage decreased. The automatic sniper rifle had it's damage decreased so you have to shoot a villager about 7 times to kill them.
Note 3: You can't use these 2 at the same time unless you toggle them with a joker command.
Note 4: You won't need to equip the thermal scope and a rifle now. But turn it on while you are playing, or things won't look correct.

Note 5: It's not a game speed modifier

A few values
40000000 - 2x speed
40400000 - 3x speed
40800000 - 4x speed
3f400000 - 1.75x speed
3f000000 - 1.5x speed
Note 6: I went through almost the entire game with this all the way up to the island, and it froze EVERY enemy. The only enemies I didn't personally check were the regenerators, the "It" boss, Saddler, and Dr. Salvador (but I bet they all freeze too. The only 2 enemies that didn't freeze were the 2 parasites that pop out of enemies heads (the 1 parasite that detatches from their heads freezes).
I could walk through bear traps and those explosive wires between walls and nothing would happen to me or Ashley.
I could skip scenes that made me mash buttons to run from boulders and whatever else. I also skipped the scene where the soldiers push the boulder off roof when I just got to the island. I walked past the knight armors that swing an axe at me too. But I couldn't skip the scene where you cut the rope on the boat after killing that giant lake monster, and I couldn't skip the scene at the end of the castle where I was chased by the giant Salazar statue. When I activated it too slow and started the part where the boulder was rolling after me, I turned it on and the boulder stopped. Then I didn't have to press X, Leon just ran slow and when the buttons popped up to dodge I pressed them.
It froze everything in the shooting gallery too, so you can take your time shooting everything in the head and then unfreeze everything.
It froze everything enemies threw or shot at me (hatchets, dynamite, flaming arrows, rockets).
When you first enter the castle and go through the first door, that's where the guys in red robes with the skull masks launch those giant explosive fireballs. It freezes those.
It freezes vehicles coming at you and whatever else.

Basically it freezes everything that can hurt you. The only bad effect is that it freezes doors and breakable things (wooden barrels, crates), so you'll want to turn it off or use it with the walk through walls code.
Note 7: I've seen it freeze rain, fog, fire, water, almost anything in the environment that moves. It also freezes 2 parasites. The sharp swinging blade parasite that comes from villagers' heads freezes, and the big worm thing that comes out of the cult guys' heads freezes. I didn't try with many enemies, but once they attacked me once they stopped attacking. It freezes the underground trolley carts you ride in.
