Emulator

Dupe issue ?

I started both... how could it be a dupe?

Issue A is how the hack is not working properly.
Issue B is about the non-hack not working properly.

I can upload a savestate should anyone want to try to get the pictograph.

Yeah, without a savegame or savestate, I don't think anybody will attempt to fix this..

Savestate=bad
Gamesave=good

Savestate from another PC, with probably different revisions and different plugins,
is bad.

I am not entirely sure if this is a problem with emulation...
Back when I eliminated the loop where the game got stuck, I had the same problem
(except that i simply didnt get a picture, only a gray screen). I rather say its
difficult to get the right view on the couple; they must be in the picture
completely, not cut off, in the moment their eyes meet.

However, I still have a .gci from that time, where i was playing around with various
revs, taking backups of my saves:

Walk over to the Photo Guy (up the ramp, into the center, the house with the
Pictograph on top), talk to him, and then walk out to wait for the guy walking his
round. He takes quite long, so prepare to wait a few minutes...

I've tried every possible angle/zoom and not gotten it, the first 2 shots i got
perfectly on the first try. All i can think of is that the logic behind "having them
stare" is not accurate enough or something around that area.

Ok a little walkthrough, you start on a little cove, go to the left then run straight
till u reach the docks, turn left and go uphill, up some stairs, turn left, keep
going up, if u look around u will soon reach a place with a windmill and a door that
has a camera on it. On that same area a woman on an orange/yellow dress will be
standing besides some wooden stairs, equip your pictograph and target here, make sure
her whole body is on the shot, now wait for a guy in greenish cloths to come by and
when they both look at each other, snap the shot, making sure both subjects are
entirely on the shot.
Once you've taken the shot, go inside the house with the camera on it, and show the
camera to the guy inside, then choose the photo you took, he will always say it's wrong.

You've got some metroid/ssmbm/sms saves as well if you'd like to try something.
I understand this is in no way a priority.
Thanks for your time ector and xtra!

Pictograph should look similar to this, which passes perfectly on my GC.

http://guidesmedia.ign.com/guides/17012/images/photoquest_3.jpg

To all devs also!!

On that very same gamecard, you've got a Metroid save, in which upon loading and
opening the door, you will encounter the biggest slowdown in the game, which i
believe is caused by the water textures. Maybe you could look into that as well.
Please pass this along since i'm not fond of IRC.

Last comment, could it be because the FB RAM option is 16bit color only instead of
32bit? Or is the GC's default FB copy also 16bit?

You mean that the moon works and the rest of the images work, but this doesn't pass
as the couple image?

Isn't that weird.

?

The postman photo works, the shaking guy photo works, but not the couple.

First 2 got em on first try, 3rd impossible to get.
I get all 3 on my first try on GC also, just tried again started a new game, it's
early into the game so it took no time, on the first try i got the couple photo
correctly.

Show the full moon to the depressed man and he gives you a chart. Does that work? It
should be the simplest hit-test.

Hmm i'd have to advance more ingame to enable day/night transitions.

Anyone tried anything at least? r2343 still unable to complete.

I can say that I haven't tried, only because I was too engaged in finding the pearls.
Now I just have to put them in the dollies and the tower will rise up (even though I
already have 2 triforce charts because I'm so awesome)

Try plz!! :P

It's a very hard job to track why it doesn't work. We don't exactly know what's going
on in the backend of this picture taking/recognizing mechanism (no, there is no small
dwarf which looks at the photos inside your computer/GC/Wii ;)) I'll try doing the
quest myself on this playthrough to see whether it works or not.

btw are you the same Federelli who retextured OoT from emutalk? If so, awesome job!
If dolphin will be fast enough the cel-shaded style could be replaced with awesome
crisp textures!

Yep it's me :), tyvm. Tho i think that to replace zelda's WW textures, the cell
shading effect (visible on characters mostly) would need to be disabled, and i've no
idea what impact will that have on gameplay.

Regarding the issue, if i had to guess, the GC does a pixel comparison with some
internal comparing algorithm, trying to detect two blackish figures at certain
positions in the shot. But i also guess somewhere it captures the "info" of them
staring at each other, and wether their whole bodies are in the shot.

no that's just insane image processing. and it would make a lot of mistakes.

My guess is, and some famous image processing experts say so too is this:

The number of possible permutations for a picture to be taken is a 6D space:
Photographer stands in X, Y, Z, aiming his camera in time T to the direction PHI, THETA.

It probably keeps these values and T is the time of day.

what are phi and theta? a quick google reveals only "phi theta honor society"...

We define that a vector v (positioned at point p1) is "looking" towards another point
p2 when v = p2 - p1.

As the distance from p2 to p1 doesn't matter (since we are only interested in the
direction), we can remove p2's coordinates (and, in the camera case, eliminate a 7th
dimension) by regarding the direction as two angles of v from the unit vectors, phi
and theta. This is also known as Spherical Euclidean Coordinates though we do not
need the length of the vector, r.

More info at http://en.wikipedia.org/wiki/Spherical_coordinate_system

sorry for the "holy hell..." comment. It was plain wrong of me.

in any case, how do I start this quest? Walkthrough?

I kinda forgot :P (I have the camera though)

Just walk over to the Pictograph guy and talk to him after he showed you his gallery.
Not sure, but you might have to show him your pictograph first. He should be standing
behind the counter for that.

Yep, go to the door with the camera above it, it's in front of the windmill, on the
highest rise in Windfall Island. He'll tell you to take certain photos, 2 of which u
will get on the first try, but not the latest one.

@XK: Thx for the phi and theta info. Sounds like something very useful :)

federelli: IIRC he only hints on what the photos should have, I want to know EXACTLY
what to take pictures of, that was my intent.

If I can reproduce this issue, I'll accept it.

marcus: np :)

Err... phi and theta are names. As are alfa and beta.

yeah they are greek letters.
alpha beta gamma delta epsilon zeta eta theta yota kappa bla bla bla omega.

Ok, walkthrough.

Once you get the camera man to tell you to take the picture of someone sending mail (#1).

Just go to the mailbox on windfall island, by the docks, stand close to the tree, aim
at the mailbox and when a man in a red outfit shows up, snap the photo as he's
putting the letter into the mailbox.

You take that photo to the camera man and show it to him, he'll give you the next
assignment, which is to take a photo of a shacking man.

For this you go to the cafeteria, which is above the shop were u got the sail. Once
inside, grab a pot and throw it to the man standing by the table, as soon as you do
that, pull the camera out and snap a photo of him shacking, take it to the camera man
and take the final assignment.

For this last one just wait outside the windmill, which is right across the door with
the camera, aim at the woman in the orange dress, and when a man in a green suit
comes by and they look at each other, snap the photo, take him to him and voila,
quest complete.

It's very frustrating since it's so easy to get on the GC, yet impossible on Dolphin.

Good luck!
Questions? ask ahead.

I'm here right now btw, so we can kinda chat it out if you want, you can delete the
comments once we'r done.

hehe, too bad I can't chat right now since I have to go.

It seems that Dolphin isn't getting my input for some weird reason in r2399, so I
can't do anything at the moment :(

I know this is nowhere near a priority fix, i'm glad it's been accepted :D, very
frustrating!! ty

Do you have the required debug tools to debug this? Seems like it's not easy at all

When you are trying to take the last picture of the man and woman staring at each
other make sure it's the right man.
Near the dock on Windfall Island, there is a big buff guy standing near the dock.
Make sure you snap you pictograph when the man that walks around all the time is
right beside her and then snap the picture.
Take my advice, don't snap a picture of the big buff guy in green and the lady in
orange. You won't be able to get them in a pictograph together anyways.......

huh?

I concur, huh???

Still not working and now you get a blue/red square on the top left of the image
(pictograph), which wasn't there before.

nah, it ever was there, use safe texture cache if you want it to go away :)
(btw, that's a pixel, a big one though :P)

as for the issue, i'm afraid this could be a PPC related one :(

Peek Color doesn't fix this either... taking pictographs now takes like 20seconds tho
:/...

Does Wind Waker use Peek Color for pictographs?

hmmm, might need a bit of thought.

Ugh i'm working right now, i'll be able to test in 1-2hrs :/ sorry.

Please compare the speeds with different anti-aliasing settings, and in dual-core and
single-core mode...

Hey there, r3818 still doesn't fix the final black and white picto-graph quest, but it
may have fixed some of the color ones maybe?

Anyone with a gamefaq save with the color pictograph could try to see if they work or
not.

Checking some other pictograph quests, one tells me i should take the picture from the
front instead of the back, when i AM taking it from the front.

Could something be upside down or similar? It seems like it could be an issue with
checking the framing as well

Taking a pictograph of Lanzo and the lady talking together inside his shop works fine.

Another thingie.

When EFB is used in heat effects, like torches, basically EFB should takes the image
and distort it with a haze effect. What happens is that:

-first it's not taking the correct depth, like if link stands in front of the torch,
link appears in the heat effect, which shoulnd't happen
-second the effect looks like it's been displaced to one side, like imagine u had a
background with the letters A,B and C, and a torch in front of letter B, the heat
effect is showing the C instead of the B (like it's shifted).

Hope u understand!

Taking a pictograph of a full moon (zoomed) doesn't work either.

Same speed for SC and DC here, around 6 secs of freezing.

With 2xAA, it takes like 4-5 minutes. (yes wait and it will complete)
With other modes it just takes forever. (not willing to wait :P)

thanks for those tests :D

yes, i just tried with AA (8xMSAA) and it took 1mn to complete...
without AA it's much faster there, I'm using Native res, safe texture cache with copy
EFB to RAM. and no filtering to avoid altering the EFB.
I'm also using dual core but as federelli said, it doesn't make a difference there.
(E6600 @ 3.4Ghz, HD4870, 32bits)

And about PEEK_COLOR, i'm sure you'd like to take a look at that Nolan.Check :
http://forums.dolphin-emu.com/thread-2529-post-24550.html#pid24550 :)
looks like one more game using it.

Any speed improvement in r3822 or later?

Not over here. r3826

no way to capture the 3rd lenzo assistant's pictograph mission. i've tried 2000++
snapshots. none would just accepted.

Please try this patch (currently for Windows version only) and describe the
performance, if there's any difference. The sun in the Wind Waker title screen may
flicker, but just ignore that for now.

Does Wind Waker use an anti-aliased EFB? Because I hear the GameCube EFB dimensions
are 640 x 264 instead of 640 x 528 in that case! Maybe we need to correct the read
coordinates in that case.

P.S. Crud! "Issue attachment storage quota exceeded." What will I do now?

Of course, the patch won't work very well because it's mangled by Google Code's line
wrapping. Ugh.

I've been waiting since yesterday for a response to a request for more attachment
quota...we've gone through 50mb in the last 3 1/2 months 8O

Anyway, use pastebin or something (and maybe delete the comment with the patch
please!).

Good idea. Please try the patch at: http://pastebin.com/m60ec7934

Wish I could help with this, but...I don't have ZWW :(

I just tested your patch and for me it breaks completely dolphin after the Dolby logo.

Ugh Nolan, could you add a precompiled .exe somewhere?

I'm not sure if this the right site to post this, but I've been testing Z:WW, and the
random black screens happen when the music changes, for example, in Windfall Island,
there are two tracks, and when it changes tha black screen happens. It isn't a
breaking game issue since you can use an item (for example pictobox) and the black
screen goes away.

Regarding that issue darkvalen21, i've gotten it too, far more often on the JitIL
version.

A video of the camera missions:

Watch until 5:30

The problem is still there in Dolphin.

Searched around the forums and found this:
http://forums.ngemu.com/dolphin-discussion/115851-zelda-ww-pictograph-bug-info.html
Is it related to this bug?

Anyways good luck.

That topic is old and already implemented - it dealt with the problem that ZWW was
waiting for the picture to show up in memory. Copy EFB to RAM does this.

However, the current problem is that the picture of the couple is not possible for
other reasons we dont know yet.

Yay Sl1nk3.s! fixed :D

federelli: it's probably much simpler than I thought - It searches for the male's
shirt color and females shirt color, so that you can see them both.

Lol funny, thinking that eventually it's a B&W image :D.

I still cannot get this shot even with revision r4034 i restarted the whole game and
have tried just about all angles and lenzo still refuses the third picture. Are there
any specific configurations, although i have tried just about every config i can
think of. I am using 64 bit does that make a difference.

currently broken in the 64 bit build (i think) see issue 615

yep, you can disable the awkward x64 optimisation in
\Core\PowerPC\Jit64\Jit_LoadStore.cpp line 200 to make it work though, but a better
fix is needed :/

I'm not sure if this is still relevant but I copied the efb to ram & I got all 3
pictograph shots. It froze a little each time but that was about it.
This is the third shot:
http://i50.tinypic.com/2hrfuwo.png

I have everything set up but the only problem is that it is a black screen but
everything else works what do I do?

Should this issue be fixed in the newer builds??? Cause he still wont accept my 3rd picture!!!

It works indeed, you need to have EFB to RAM and EFB Access activated, i'm not sure if it works using DX11 plugin but it does work with DX9 and OGL plugin.

Still doesn't work for me, not sure if im doing anything wrong but even with EFB to RAM and EFB Access activated and wether it is with DX9 or OGL, he still doesnt accept the 3rd picture and i absolutely refuse to cheat.

DX11 is too buggy for me so i avoid using it.

I have the same problem. The first picture was accepted after a few tries, the 2nd on the first try, but no matter what I do he won't accept the 3rd picture.
Tested with the latest revisions (64 and 32 bit), EFB to RAM and EFB Access activated.
Also tried to play with the configuration (DX9 and OGL), e.g. disable EFB Access which fixed the lag after taking a picture, but I just can't get it to work.

Just tried it with Rev. 5021 (just randomly picked one that was released at about the same time as the comments above) and got it on the first try.

@w4yne1337: Which options did you use for rev 5021? Please

DX9 plugin with EFB Access and EFB to Ram activated. Nothing special otherwise.

@w4yne1337: Thx man. Finally i complete this side quest. Using r5021 i got 3rd photo on the first try. In the new revisions i cant make this quest, only in r5021.

Could you possibly verify whether r5020 fixed this (by trying out r5019 and checking if it fails)?

On a second look: Can you try the OpenGL plugin in recent revisions with the same settings? It might not be implemented correctly in DX9.

Try r6778 and later.

Just tried r6778 and the camera image is all screwed up when I take it. Not sure if it's a setting doing that or what.

You'll still need "EFB to RAM" aswell as "CPU->EFB Access"; and bear with the lag that occurs when taking the picture.

Should work in r6780 (there was a EFB to RAM bug introduced in R6777 ...)

Hello guys im with the same problem but with first photo of the postman,the guys of photos don want accept the first photo of the love guy,i tried everything and he dont want accept :(

FIXED

I was having the same problem with the third picture. I'm using r7668. You have to uncheck EVERYTHING under "hacks" on graphics configuration (except for "RAM"). It will run really slow like this and when you snap the picture it'll take a few seconds to a minute to register, but it works.

FIXED JUST LIKE COMMENT 98 IT IS NOT REQUIRE THAT ESPECIFIC REVISION Y COULD BE SOMEONE REVISION FURTHER

THANXS

Was unable to get the pictograph working in any way (not even the moon was recognized). Tried a bunch of revisions and configurations, nothing worked. What finally fixed it for me was >OpenGL< ! Just switched from D3D to OpenGL and suddenly everything worked flawlessly, not even any lag/freeze after taking pictures and everything was recognized as in the original game! Try OpenGL if you can't find a solution, and just crank up the graphics settings in OpenGL to make it look (almost) as good as D3D!

I've tested now with 3.0-815. Not only Lenzo didn't accept even the 1st pictograph, but the game froze when I tried a second (generic) one. I'm afraid this issue is far to be really fixed...

I've done some testing with this in 3.0-862 and I have finally got the 3rd picture working consistently. D3D9 was the easiest to get working, just EFB to RAM and CPU can access EFB. For both DX11 and OpenGL it also had to have Anti-Aliasing set to None.

None of these things seemed to have no effect on the picture recognition: Anisotropic filtering, Scaled EFB Copy, Per-Pixel Lighting, Texture Cache Accuracy, External Frame Buffer, Enable Cache (for EFB copies section), Internal Resolution.

In the end, and in this latest version it seems all you need is to make sure EFB to RAM is set and Anti-Aliasing is turned off.

Using just OpenGL gets the picture recognition working for me. And EFB copies to RAM with cache enabled makes it work for me on any backend but OpenGL was the only one that allowed me to hand in the 3rd picture on the first try. Duplicated this over and over again so for me, DirectX 11 and 9 don't like it. Other settings such as AA, AF and resolution have no effect except on fps, frame buffer settings have no effect either for me. This is on the latest developer build, can't remember the exact version.

OpenGL worked for me. I spent so damn long trying to figure this out.
