Hello. I wanted to ask a question about what is possible when it comes to save hacking and editing. Could I get 100% saves for games and how easy is it to use them, or are there other comprehensive ways to do this? Thanks!
What about pcGecko and the like?Saves are encrypted and nobody has found a way to decrypt them yet..
They don't seems encrypted to me.
I can read my character's name or save profile name by editing them on hex editor.
Savegames often contains a checksum to verify the data integrity, if you edit a value you might have to fix the checksum too or the game will report it as corrupted.
To start doing savegame hacking, just create multiple saves, with very few changes (HP, level, names, save place, etc.) and compare the files to see what's different.
some game have a very easy savegame data format (if it's only a list of completed level, like captain toad) to very complex one (like RPG, xenoblades, ass creed, etc.)
Do not forget to update the CRC32 after editing.That's odd, I tried reading my Mario Kart save and it was giving me problems. I must of been using the wrong tools.
There are a couple ways you could do this. One, do a memory dump of the screen buffer, but I don't know what the screen buffer address would be in that program, or if you would have problems like I did when I was dumping the screen buffer in the U-Paint program I made for the Wii U. When I would dump the screen buffer, instead of dumping it as RGBARGBARGBA in the dump, it would repeat everything four times, so the dump was RRRRGGGGBBBBAAAA and so on. The other option would be to share the dump files of your saves so others could reverse how they are saved. I do not have that Art Academy Sketchpad, so I would not even be able to start helping without being able to look at the files to reverse them, nor would other people without that program.Sorry for the double post.
Really nobody can help me? Not even an hint on what I should do?
In all these years I saw lots of troll threads flooded by people feeding the trolls, with troll posts and other stupid comments, really people on this community prefer troll threads to someone who is asking something giving explanations and details, and the something asked is not an IOSU exploit?
I don't want other people doing the work for me, but I'd like at least someone more experienced by me that tells me what I can do.
(for people who don't want to read, just leave the thread plea- no, I mean, I need to extract some drawings made using Art Academy Sketchpad at full resolution, 1920x1080 and with less compression as possible, I don't care how. Some possibilities are, converting the drawings into Atelier/Home Studio format that can export them in JPG, extract them from the savefile, or do something with the PC emulator, but I have no idea of what I should do, I even tried the hex editor on the savefiles with no results).

You can definitely see that there are images in these files. One easy one I extracted looks like this, I didn't worry about correcting the colors though -Thank you very much for the help, you also gave me an idea of a try that I should do (do a copy of the drawing with a little point on a corner to see what's the difference in the file, and see if the numbers can be converted into RGB values)... as I wrote a couple of posts ago, I'm a bit noob, I have basic knownledge but I have no experience.
I uploaded some saves so you can experiment with them if you want... they are not located in the correct folder, but it shouldn't be a problem I hope.
These are not the only artworks that I want to extract, it's just one, when I will discover the way to extract them I will do the others.
Art Academy has an option to fix/dry the artwork. When you do this, the former artwork becomes impossible to modify and you can only draw over it ignoring the color mixing influence with the fixed part (the older part becomes a sort of background).
I exported the artwork in 2 versions, with and without the fix.
I will do the other experiments soon, If I will be able to find the corners of the artwork, I will be sure that all the data between the corners is the image, so it would be easier to extract (I assume that I should fix every artwork, so it's easier to export them).
These are the saves:

Edit: Here it is in full resolution - https://onedrive.live.com/redir?resid=9525F351E1619336!715&authkey=!AECIiCeLHw1bLtY&v=3&ithint=photo,bmp
I saved it in BMP format, but it had a JFIF header on it, so it may be slightly compressed, but the format I saved it to isn't compressed, so you can see exactly how it looks after extracted.
Hey, no problem, so is that good enough quality for you? I can give you the exact offsets to extract if it is.How is that possible? -.- I... I don't even...
Thank you anyway!
So, well, despite this, I'm not able to do it by myself I think, if it doesn't bother you too much, would you like to tell me how you have extracted it?
(If you want I can give you the other pictures in PM, if it's so easy it wouldn't take you much time, they're 5 in total (4 because one is already extracted now), but it would be better if I learn how to do it by myself, I would really like to learn it...)
Thank you very much! It helped a lot!
EDIT:
I'm currently reading this: https://www.w3.org/Graphics/JPEG/jfif3.pdf I hope it will be helpful to learn how to recognize the pictures in the files
EDIT2:
I'm finding a lot of forum threads and tutorial about how to find JPEG files into HEX streams, yes knowing that the pictures are in JPEG format inside the files really solved my problem, now I think that with a bit of research I'll be able to extract them, probably. Thank you!

No problem, this was something I used to do a lot when modding, so it was pretty easy, and it's good that you could figure out all the rest on your own.Did it!

It's a lot easier once you know what to search!
I learned a lot of things today, thank you!
(the lenght of the file is written in the header, so once you find where it starts, and it's easy since there is even the JFIF text lol, finding the end of the file is not a problem).
I need to practice a bit with the other files, but anyway it's not that hard now that I know how to do it.
Thank you again!
