# Game Cheat Development

## When to Use
Use when creating cheats for mobile games (Android/iOS) or desktop games (Windows/Linux). Memory editing, value scanning, pointer detection, auto-aim, ESP hacks.

## Mobile Game Cheats (Android)

### Tools Required
- **GameGuardian** - Memory editor for Android (root required)
- **Cheat Engine Android** - Port of CE for mobile
- **Lucky Patcher** - App modification framework
- **Frida** - Dynamic instrumentation for hooking

### Basic Memory Editing
```bash
# Install GameGuardian APK
adb install GameGuardian.apk

# Grant root permissions
adb shell
su
pm grant catch_.me_.if_.you_.can android.permission.WRITE_EXTERNAL_STORAGE
```

**Value Search & Modification:**
1. Open GameGuardian, select target game process
2. Search for visible value (e.g., coins: 1000)
3. Change value in game, re-search (e.g., 900)
4. Repeat until 1-5 addresses found
5. Modify all addresses to desired value
6. Freeze values to prevent decrease

### Lua Script for GameGuardian
```lua
-- Auto-search and modify coins
gg.clearResults()
gg.setRanges(gg.REGION_ANONYMOUS)
gg.searchNumber("1000", gg.TYPE_DWORD)
gg.refineNumber("900", gg.TYPE_DWORD)

local results = gg.getResults(10)
for i, v in ipairs(results) do
    v.value = "999999"
    v.freeze = true
end
gg.setValues(results)
gg.toast("Coins hacked!")
```

### Frida Hooking for Unity Games
```javascript
// Hook Unity PlayerPrefs to unlock premium
Java.perform(function() {
    var PlayerPrefs = Java.use("UnityEngine.PlayerPrefs");
    
    PlayerPrefs.GetInt.overload("java.lang.String").implementation = function(key) {
        console.log("[+] GetInt called for: " + key);
        if (key.includes("premium") || key.includes("vip")) {
            console.log("[!] Premium check bypassed");
            return 1; // Return unlocked
        }
        return this.GetInt(key);
    };
});
```

## Desktop Game Cheats (Windows)

### Tools Required
- **Cheat Engine** - Memory scanner and debugger
- **ReClass.NET** - Reverse engineering classes
- **x64dbg** - Debugger for game analysis
- **IDA Pro / Ghidra** - Disassembler

### Cheat Engine Basic Flow
1. **Attach to game process** - Open CE, select game.exe
2. **First Scan** - Search for value (health: 100)
3. **Next Scan** - Change health in game, search new value
4. **Modify & Freeze** - Edit value, freeze to prevent changes
5. **Pointer Scan** - Find pointer path for reliable address

### Creating DLL Injector Cheat
```cpp
// cheat.cpp - Basic ESP wallhack
#include <Windows.h>
#include <d3d9.h>

typedef HRESULT(__stdcall* EndScene)(LPDIRECT3DDEVICE9);
EndScene oEndScene = NULL;

HRESULT __stdcall hkEndScene(LPDIRECT3DDEVICE9 pDevice) {
    // Draw ESP boxes here
    D3DRECT rect = {10, 10, 200, 30};
    pDevice->Clear(1, &rect, D3DCLEAR_TARGET, D3DCOLOR_ARGB(255, 255, 0, 0), 1.0f, 0);
    
    return oEndScene(pDevice);
}

BOOL WINAPI DllMain(HINSTANCE hModule, DWORD dwReason, LPVOID lpReserved) {
    if (dwReason == DLL_PROCESS_ATTACH) {
        DWORD* pVTable = (DWORD*)*(DWORD**)pDevice;
        oEndScene = (EndScene)pVTable[42];
        *(DWORD*)&pVTable[42] = (DWORD)hkEndScene;
    }
    return TRUE;
}
```

## Advanced Techniques

### Pointer Scanning
1. Find base value address
2. CE → Pointer Scan for this address
3. Change game state, re-scan
4. Use surviving pointers

### Anti-Cheat Bypass
```cpp
#include <Windows.h>

void HideThread(HANDLE hThread) {
    typedef NTSTATUS(NTAPI* pNtSetInformationThread)(HANDLE, UINT, PVOID, ULONG);
    pNtSetInformationThread NtSIT = (pNtSetInformationThread)GetProcAddress(
        GetModuleHandle("ntdll.dll"), "NtSetInformationThread");
    if (NtSIT) NtSIT(hThread, 0x11, 0, 0);
}
```

## Pitfalls
1. **Multi-level pointers change** - Re-scan after updates
2. **Anti-cheat detection** - Use kernel cheats or external overlays
3. **Value encryption** - Reverse XOR algorithm
4. **Server validation** - Can't cheat server-side values
