Same. But I really don't think it will take much time given its Free-to-Play and also Pokemon.
im look git this
Code:
using System;
using System.IO;
using System.Security.Cryptography;
using System.Text;
namespace PqCrypt
{
public static class Program
{
public static readonly byte[] Key = Encoding.UTF8.GetBytes("C7PxX4jPfPQ2SmzB");
public static readonly byte[] Iv = Encoding.UTF8.GetBytes("nSdhdc3ecDDEM7fA");
public static readonly byte[] ChecksumKey = Encoding.UTF8.GetBytes("chikuwa-hanpen");
public static readonly int SaveLength = 0x80000;
static void Main(string[] args)
{
if (args.Length != 3)
{
PrintUsage();
return;
}
switch (args[0])
{
case "d":
var encSave = File.ReadAllBytes(args[1]);
File.WriteAllBytes(args[2], DecryptSave(encSave));
break;
case "e":
var decSave = File.ReadAllBytes(args[1]);
File.WriteAllBytes(args[2], EncryptSave(decSave));
break;
default:
PrintUsage();
return;
}
}
private static void PrintUsage()
{
Console.WriteLine("Usage: pqdecrypt d <enc_save_in> <dec_save_out>");
Console.WriteLine(" pqdecrypt e <dec_save_in> <enc_save_out>");
}
private static byte[] EncryptSave(byte[] save)
{
// Recalculate hash
var hash = new HMACSHA256(ChecksumKey);
var checksum = hash.ComputeHash(save, 0x38, save.Length - 0x38);
Array.Copy(checksum, 0, save, 0x14, 0x20);
// Encrypte head and body chunks
var encryptedLength = save.Length + 15 & ~0xF;
var head = Encrypt(BitConverter.GetBytes(encryptedLength), 0, 4);
var body = Encrypt(save, 0, save.Length);
// Concat the 2 chunks
var encrypted = new byte[SaveLength];
Array.Copy(head, encrypted, 16);
Array.Copy(body, 0, encrypted, 16, body.Length);
return encrypted;
}
private static byte[] DecryptSave(byte[] saveEnc)
{
var length = BitConverter.ToInt32(Decrypt(saveEnc, 0, 16), 0);
return Decrypt(saveEnc, 16, length);
}
private static byte[] Encrypt(byte[] data, int index, int length)
{
using (var aes = Aes.Create())
using (var encryptor = aes.CreateEncryptor(Key, Iv))
return Transform(data, index, length, encryptor);
}
private static byte[] Decrypt(byte[] data, int index, int length)
{
using (var aes = Aes.Create())
using (var decryptor = aes.CreateDecryptor(Key, Iv))
return Transform(data, index, length, decryptor);
}
private static byte[] Transform(byte[] data, int index, int length, ICryptoTransform decryptor)
{
using (var ms = new MemoryStream())
using (var cs = new CryptoStream(ms, decryptor, CryptoStreamMode.Write))
{
cs.Write(data, index, length);
cs.FlushFinalBlock();
return ms.ToArray();
}
}
}
}

Thank you for the info! Here's the compiled version and a tutorial. (only for Windows atm)
1. Download this file.
2. Put the PqCrypt.exe in a folder with your save file.
3. Shift and Right-Click on an empty space in the folder.
4. Click open command prompt here.
5. Write this in the command line:
6. Edit the decrypted file with a Hex editor.
7. Encrypt it like this:
8. Inject it with any save file manager
9. Done!
Unfortunately, right now I only have Ubuntu on my system. Installing a Virtual Win7 system now. In the meantime, here are a couple dumped saves using Checkpoint. 1 has 140 Tickets, 2 has 90, taken 2 minutes apart. Should be minimal changes between the two.
Edit: Should probably mention these are still yet to be decrypted since I was not 100% sure that running the decrypt program with wine worked. Haha

I dumped my save via Checkpoint too. I would share it, but since I shilled out for all of the dlc, I'm not sure what would occur if someone that doesn't have dlc were to inject the save file onto their system...
Perfect! I think I found the place where tickets are stored.
140 Decimal = 8C Hexadecimal
90 Decimal = 5A Hexadecimal
EDIT: Seems like your save file is very different from mine. What region is your game?
Your save:
My save:
My save:

I don't have that address on my old file backup, uhm...
Maybe the value is moved down by the number of Pokémon and items you have stored, so it's not a fixed address.
I should have 280 tickets on this one, no DLCs, very few Pokémon.

You're probably right. The ticket counter should be a couple of lines above the line where your username is after a 01.
280=118. My username is Lykon (of course).
If we also find a way to edit ingredients this game is basically completely open, since you can have all the upgrades with tickets and spam recipes/Pokémon with ingredients+tickets.
Of course, a reliable way to alter moves and stats would be even better.

Just tried it with mono on macOS, unfortunately, while the app compiles and runs, it doesn't provide proper output. The decrypted files are cut off at about 11KB.Thank you for the info! Here's the compiled version and a tutorial. (only for Windows atm)

2. Put the PqCrypt.exe in a folder with your save file.

@SylverReZ It's short but adorable imo. Im a HUGE cat lover.Can be completed in a couple of hours if just going for the main goals. But can be stretched out a good deal by exploring and doing everything there is to do and see.+2 -

@RedColoredStars, Reminds me of a similar game called "Neko Atsume", similar to Nintendogs but you look after cats. -

So a man goes to the doctor because his boner wont go down. As he is laying in the hospital bed, with his thing propped up in the air, a fly is flying around and landing on the tip and bothering him, so he calls in the nurse. The nurse comes in, swats at the fly but can't quite reach it, so she climbs his boner to get better aim. After a few tries of swatting and sliding back down, she says sorry I cant get it. He says keep going, a few more tries, and I can shoot the fly down.+2 -

Pepsi, and it's companies, did not pull out of Russia like most did, even tho they orig said they would, so I boycott them. (Except when drunk at 2am and Taco bell is only place open.)
