[TAS] Doom SNES - Nightmare 100% Full Walkthrough in 56:23 by Dimon12321
210This is a tool-assisted superplay that beats all the maps of SNES Doom on Nightmare difficulty. It's not the fastest possible, but it doesn't have any waste-of-time moments for sure. There are 3 maps where I didn't get 100% of kills or secrets by minor mistakes, but it's forgivable, I think.
Yeah, that's right! You've found a crazy man who did that! I was curious, how a TAS of such a poor version of Doom would look like, so I tried something and here we go.
------- About the game -------
The movement is so laggy I can barely go wherever I want to in that slow motion, so I set the speed to 25% to have some control.
The aiming system is decent, but you need to get used to it. After you press Fire button, the game does the damage calculations first and than begins to produce all those animations, like gun shots and monster deaths.
The random is predicatable. When no monsters are awake and they don't detect you, you will deal the same amount of damage if you shoot now or 1 second later.
The pistol is more powerful than in any other version of Doom. It's damage varies from 4 to 24. That means you can kill a zombieman with a single shot.
The shotgun is generally better than the pistol because it's reloading speed isn't that long and it's very powerful at times. The damage can be divided into 3 ranges:
- 28, 32 - some "weak" or "inaccurate" shot. I don't know how the game decides if it was inaccurate or not, since I've made a lot of shots like that, which inflicted much more damage. It's often happens when you hold the fire button and shot as soon as the reloading animation is finished.
- 64 - some kind of medium shot.
- 96, 118 - some kind of deadly shot.
Probably, the overall damage depends on the power of a single bullet and then it's multiplied by 6 or 7.
The chaingun is more powerful than the pistol. It's damage varies from 3 to 32. Highly relies on the random. Not the best choice, since manipulating damages decreases its firerate dramatically. Still, it's sometimes better than the shotgun.
The rocket launcher requires a lot of skill not to blow yourself.
And it's blast range is big too. I barely understand how the game decides which objects should be damaged with it. See my pre-final rocket shot on E1M8. I don't know how that demon died because it was as far away from the blast as me.
The chainsaw's damage is higher too, but the firerate is slower. The damage varies from 6 to 48. While testing, I got those damages: 45, 18, 24, 48, 12, 42, 15, 6.
Demons have 140 hp instead of 150, like in all other version of Doom. I think it's done to be able to kill a demon with 2 shotgun shots more often.
----------------
Don't know why, but I like Episode 2 the most of three. The plasma gun and the rocket launcher made the walkthrough more spectacular and it wasn't that long and repetitive.
I discovered the method of finding 2-byte health addresses of such strong monsters as Cacodemons, Barons of Hell and the Cyberdemon, which helped my manipulate damages and eliminate them easier. I have shown the possibility of killing a cacodemon with a single rocket and a baron of hell with only 2 rockets. Too bad, I didn't discover it while TASing E1M8.

I'm not sure if there were much sense in upscaling native SNES resolution to 4K (2880x2160, according to 4:3 aspect ration), but maybe someone will find it useful.
