That was a nice April fools video!
In other news: The glitched run might not be able to progress very far. I was just testing an alternative Wall Market strat and the game crashes after the battles with Corneo's friends (infinite black screen)
Luckily this battle is avoided by having Cloud picked by the Don. But who knows where the next unavoidable crash may lie :-P
I have a bad feeling about the forced Battle Square battle(s).

Well, time to continue the ff7 tas.
What are some ways of finding a text-box (skip) memory address?
I can write the lua script, I just don't have experience of finding such an address, and the next segment is a giant wall of text boxes.
Lua was broken before it was removed. If you can fix it and get it to run, the other devs might be willing to merge it back in, but I'm guessing they would probably be against it unless someone can step up and maintain it this time.
It broke? I'm using an old version of dolphin and lua works fine, at least for my needs :-P
It doesn't have controller input implemented yet though.
Too bad.

i managed to fix emu.frameadvance() function. so it now works!
However, I'm getting false positives.
Could I use memory.registerwrite to make sure I only get the value printed (or even better: written to txt file) when it changes?
I don't want to get the same value twice or more in a row.
I used this:
-- File to write to
local outfile = assert(io.open("value_mem.txt", "w"));
memory.registerwrite(0x00c7500f,outfile:(memory.readbyte(0x00c7500f)))
end
assert(outfile:close());

Dolphin emulator.
Hmm, that's too bad then.

So, which emulator are we talking about?
If emu.frameadvance() isn't recognized (like that) then it won't run the WHILE statement once per frame. So, if you remove it, it will run indefinitely when you open the script & that's likely the reason it floods the dialog & crashes...

A friend of mine had some of his videos removed by youtube because someone submitted a copyright claim against him.
The issue is that the videos are of a 'livestreamed' video game.
The friend recorded a video game tournament that was freely broadcast as a live stream.
The person who filed the complaint does not, of course, own copyright of the game. Sony/Nintendo own the copyright of the game.
I thought this case was quite interesting.
So, can someone be successfully sued for uploading a livestream of a gaming event to youtube? The gaming event was broadcast freely on a livestream website. 90% of the videos are of the game being played, as opposed to the 'event' itself.

I like using modulo best
local timer = 0
while true do
timer = (timer + 1) % 60
emu.frameadvance()
if timer == 0 then
print(memory.readdword(0x80000048))
end
end
This is what I need except can it be modified so that it bases 'seconds' on something else? Based on any type of clock, including the OS if necessary.
(emu.frameadvance() doesn't work properly in this emulator and just floods the lua dialog with values as fast as it can, and crashes.)

ok, so I think I've made this more complicated than necessary.
All I actually need is something that does print(memory.readdword(0x80000048)) every second (60 frames).
Anyone can help with this?

I want to print the value at 0x80000048 everytime it is written to.
Anyone know how this can be done?
I only know that I'll have to use this function, but I'm unsure how to have it print only when the value is written. (so it doesn't print anything when the value isn't changing)
print(memory.readdword(0x80000048))
Thanks if anyone can help with this.
edit:
or an alternative way would be to print the value every 3 seconds!

this is antd (i suppose everything posted today will be interpreted as april fool's)
combined with the data error glitch we should be looking at sub 4 hours at least
i'm in the middle of a draft run using only manually tested warps
(and yes I'll continue to work on the non-warp run)
i will need lua scripting help for finding the most optimal warps though (pm me if you can help: http://tasvideos.org/forum/profile.php?mode=viewprofile&u=1936)
once my username is back i'll post more

Glitched run is only for the fastest time. Nothing else. It will act as a benchmark until better glitches are found.
People in the speed running community are curious to know the fastest time possible. So am I.
Enemy lure only affects world map battles. The chart only shows field battles.
All world map battles can be avoided simply by changing direction for one frame, so no time loss and no strategy needed. Field battles are where the strategy is required.
I don't think anybody has asked that question :-D

Btw, im talking about the "data error" or glitched run. There will not be any battle actions:

I've tried skipping Cosmo canyon and i could not find a way.
Nobody has reproduced it and no reputable source has witnessed it. The only source seems to be that random video.

Estimated Min. time saved = 2729 seconds (45.483 minutes)
If as fast as Farringa's run:
estimated worst end time = 6 hours 55 minutes
Depends if the PSX version can keep up with the PC version.
There are tons of other time savers that are not in this estimation: Eg. general TAS playing and non-battle time savers.

This script worked in the beginning of the game for skipping text boxes:
Dialog= 0x000832A0;
while true do
for i = 0,5,1 do
X = memory.readbyte(Dialog+i*0x30);
X = X % 8;
if (X == 6) or (X == 4) then
joypad.set(1,{["circle"]=true})
end;
end;
emu.frameadvance();
end;
But now it no longer works.
If anyone has coding experience, can you modify it so it works for this section of the game?

Yep, stutter makes the red line rise less quickly.
Menu glitch: Enter the menu on the exact frame you get a battle. This removes the battle or white line.
Hmm, technically no automatic battles. But in practice there will be white lines everywhere once you reach very high danger values. Resets to 0 after 65535.
We haven't found anyway of resetting the danger value yet (only resets when you Save (slow) or enter a battle)

Actually DarkKobold is right. If a menu glitch is used, then you'll have to get into a battle before a boss. Using a menu glitch creates a repeating boss battle if you don't enter a battle before a fighting a boss.

Edit: Ok, I have implemented my idea now. The implementation (C++) can be found here. I had to guess some of the factors needed, and I didn't have the encounter sequence available, so I generated one randomly in the program. This means that you can't just run the program and use it directly - you have to fill in the correct encounter sequence and costs. So really, this is just a demonstration of an algorithm that solves the problem brute force, but hopefully still fast enough.
I'm not sure how long the segments will be. It seems they will be fewer than 6000 steps.
Thanks! I'll try to compile.
If anyone wants the spreadsheet data, you can PM Brutalal for it (it is his creation)

Brutalal has created a spreadsheet that plots the optimal path (in terms of number of steps needed to run through a field). It details exactly when you will encounter a random battle and allows many configurable options on how to avoid them.
The problem is there are many ways of getting away from a battle:
1. Accept the battle and instant escape (685 frames)
This also reduces the danger counter to 0 (you get more battles as the danger counter rises)
2. Menu glitch (83 frames)
This glitch avoids a battle but the danger counter remains (eg, if you do 20 menu glitches in a row, you'll be getting a battle every few steps)
3. Stutter Walk (x frames)
This is clearly the fastest way to avoid a battle. The danger counter remains. The spreadsheet calculates how much stuttering is needed. You lose time for every stutter, but it is a tiny amount.
So we know that the battles are entirely deterministic and we even have a spreadsheet which shows the field lengths and when the battle will occur.
This is a segment in the game. The X axis are the steps and the Y axis is the danger counter. The white lines are the battles. You get a battle when the red line hits a white line.
What we need help with is in calculating the fastest way to avoid battles. In other words, should I menu glitch, stutter (sometimes not possible, easy to see when it is or not possible) or accept+escape a battle.
So, I want to know the fastest way through the segment I just posted above. Ideally we will need to optimise the data not just for one segment but for the entire game.
Anyone that can give ideas on how to accomplish this?
