This topic is for the purpose of discussing #4785: CogneatoSwitch's NES Nobunaga's Ambition "17 Fiefs" in 23:24.39

Wow, this is a far faster time! Good to know that switching to the highest difficulty revealed a much faster strategy, as a result. Would you like to go ahead and cancel your previous submission? Also, just to clarify, optimizing by seasons is the slower of the two options?

The old one has been cancelled. Yes, optimization for seasons would be much slower, as starting a war would save a few seasons, but each war takes about 25-40 moves, or 3-5 minutes. The resulting video would showcase much more the war strategies, such as bait-and-conquer, ambush, or even gaining fiefs by killing the leader (some of these are seen in the first video). Because of the drastic difference in presentation, I propose that the type of optimization be a separate branch.

Great! Glad to see this! :)

Extreme Robin Hood tactics!

Apparently, giving peasants rice is the only way to find quality ninjas!

Link to video Temp encode. For the record, yes, there's no sound for a vast majority of the video. It was disabled in the TAS itself (around 0:27 in the encode... y'know, when the sound stops) to reduce lag.

Samsara, thanks for encode. Short movie looks like Storybook. CogneatoSwitch, You thought about subtitles (don't know possible in Bizhawk)? Are you planning make more KOEI strategy? For example SNES/Genesis Genghis Khan.

Sure, I will add subtitles next time! So to understand the oddities in my run, first recognize how I'm making it. I've generated a series of scripts that execute specific commands quickly. Thus, when I make the video, I merely execute the scripts in the right order. When I initially made the GPR script, my goal was to improve wealth and loyalty, which is useful for gaining more money. By default, I had it give 25% of total rice. I can move the number down to 1, but it messed with other scripts down the line, and occasionally changed the RNG. Thus, changing the default rice value meant redoing the whole video. Since I plan on remapping it anyway, I went ahead and submitted it on the off-chance I run out of energy to do this TAS. Stats: Drive is the only one that isn't necessary. Luck and IQ both play a part in assassination, but I can't seem to manipulate them as well as I can Char. I suppose a moderately high health score would be acceptable, as long as I didn't die from sickness. Also, changes to this area also affect the RNG "seed", which means remapping the entire game. I'm not inclined to change this because the savings is so small and I already know this seed. I haven't figured out the random events or the next-season turn order. My only solution for them is to adjust my actions. I've found the choice of action, rather than intensity, makes the most difference. For example, choosing "Send" instead of "GPR" might change the outcome. I also noticed that the event happened anyway, it just changed where it landed. I don't think there is much savings to be had there; maybe a few seconds at best. In a battle, unit movement always goes from 1 to 5, with 2 and 3 being the most powerful units. I typically send the 4 or 5 to get killed by the enemy's 2 or 3, and save my 2 and 3 to kill the enemy's leader. In this particular video, it didn't matter. However, I agree that changing the assignments before the battle will greatly enhance speed, even if it costs a whole season. The biggest bottleneck I've found is not using grants. The granted fiefs deliver 1 Char 50% of the time, so if I granted them all, it would take twice as many seasons but 1/3rd the time, with an estimated savings of 7 minutes. The next biggest is the GPR values, which were used 81 times and could easily save 2 minutes. Making assignments before the last battle may save a few minutes (assignments are slow, and the whole season will have to go by). Changing the bids might save 15 seconds and being looser on the stats selection might save 8 seconds. So I guess I predict a better video that is 13 minutes or less in length.

First Start with this: View > Display Subtitles Subtitles within BizHawk requires right clicking the game screen itself, a menu will pop up. Choose Add Subtitles to place subs in at that said frame. To modify the subs do the same thing as before but select Edit Subtitles. To note: Subtitles will be converted to an .srt format, so if you do have your subs placed around in "random" areas they will be set straight to the bottom. See Langrisser 2's TAS for example. Edit: Looking over your TAS it's fairly sub optimal. For starters 'cause it's my favourite part, is that you're end input could be ended my sooner than where it does. (84374 not 84388) The second notable part, is that you're doing input like this: Down,*Lag Frame*,Down Your input won't register since this happens. This occurs quite a lot in your TAS. Even if the case is meant to be like: Down,*Lag Frame*,Down,*Blank*,Down. You still have the chance of that blank frame being the frame you want to hit down on instead. This last one probably gets factored out due to RNG. Terrible startup to the game. Please don't use the Autofire in your input.

CogneatoSwitch, to elaborate on what Spikestuff addressed, using auto-fire isn't the best method to use when TASing. You'll want to get into the habit of using frame-advance and manually attempting to advance menus, and such, at the earliest possible frame. I made a brief test run, up to the stat creation screen, that saved 6 frames just on optimizing input. Also, and I don't know how this would affect your scripts, but I saved over 300 frames at stat creation by getting values that were just below the max allocation of 109. I stopped before deciding on IQ since finalizing from there will determine the initial RNG seed (otherwise, the AI sent a Ninja toward my fief for the game's very first move!). Anyhow, this isn't necessarily grounds for rejection; just me chiming in and sharing tips for better TASing. I'm still in the process of judging your run, and should have a final decision made later on in the day.

In a battle, unit movement always goes from 1 to 5, with 2 and 3 being the most powerful units. I typically send the 4 or 5 to get killed by the enemy's 2 or 3, and save my 2 and 3 to kill the enemy's leader. In this particular video, it didn't matter. However, I agree that changing the assignments before the battle will greatly enhance speed, even if it costs a whole season.

I communicated what I was trying to say poorly. There is a mechanic in the game--I'm going to look it up--that lets you reassign your army units, and you can assign 4 and 5 out of the picture entirely, meaning you have fewer input spam to deal with. Yes, checked it out and it's the assign command on the second page. Now what I can't remember is if that affects a "worldwide" change or if it only makes a change in the fief where you do it. But it's possible that getting rid of units 4 and 5 prior to the final battle in Fief 4, with all the other fiefs on direct, would save time in the long run because of both larger quantities of men in units 1-3, and also not having to move as many units each turn.

Yes, in the future I shall end it sooner. I thought it would make for a better show, rather than worrying about the absolute shortest. What on Earth is Autofire? I hand-crafted every script, and autofire wasn't one of them. What is the effect of it, and how can I avoid recreating it? It sounds like you want a minimal input style, rather than a stream. That is, when I need to press "down" to change numbers, I should press it for exactly 1 frame and wait until the lag frame passes (3 frames, typically) before pressing again, rather than press-and-hold for 4 frames, or toggle on/off every other frame. Is that correct?

The opening sequence is the least optimized, as it is the rarest script used. Also, I purposefully wait frames in the beginning to speed up the stat selection; the RNG seed starts as soon as the game begins, and so waiting frames earlier results in faster stats selection. I believe you are correct that I can save some time by ignoring Health and Drive to an extent; Health leads to sickness and (I think) plague, and Drive keeps enemies from attacking. Luck is tricky, because it's difficult to change after the game start, and if it is 30 less than the enemy's, ninjas will fail. Since Fief 13 has the highest luck and is one of the quickest killed, I believe it is faster to spend time at the stats screen rather than use seasons to increase luck. Char+IQ are directly needed to assassinate. I spend a majority of the time increasing Char so I can assassinate Oda. Thus, spending extra time at the beginning to maximize the stats saves me a huge amount of time later in the game. Overall, 6 seconds are not worth "saving" if only to spend 6+ seasons recouping the lost stats. Similarly, "saving" a few frames at the beginning isn't worth having to wait 10+ seconds for the better stats. That said, I only checked the first few wait frames (I've dubbed them "seeds"). It may be faster to wait longer on the title screen so the stats maximize faster.
