Create custom codes for nsmbw C++

Answer 1

Creating custom codes for "New Super Mario Bros. Wii" (NSMBW) involves modifying the game's memory values, which typically requires some understanding of how the game and its memory are structured. This process is commonly done using cheat tools like GeckoOS or through custom loaders that can inject and modify code at runtime.

Below is a simple example of what such a code could look like, written in C++, assuming you have a basic framework to apply these patches:

```cpp
// Example custom code: Infinite Lives

#include <iostream>
#include <cstdint>

// Memory address for player lives (example address, need to verify actual address)
const uintptr_t PlayerLivesAddress = 0x8034E788;
const uint8_t InfiniteLivesValue = 99;

// Assuming we have a function to write to memory in the NSMBW game process
void WriteToMemory(uintptr_t address, uint8_t value);

// This function would be called to apply the infinite lives patch.
void ApplyInfiniteLivesPatch() {
std::cout << "Applying Infinite Lives Patch..." << std::endl;
WriteToMemory(PlayerLivesAddress, InfiniteLivesValue);
std::cout << "Patch applied successfully!" << std::endl;
}

// Example implementation of the write to memory function
void WriteToMemory(uintptr_t address, uint8_t value) {
// This function would contain the actual implementation to write to game memory
// The actual implementation can vary depending on how you're injecting the code
}

int main() {
// Applying the patch at game start or on a trigger
ApplyInfiniteLivesPatch();
return 0;
}
```

Note:

1. This code serves as a high-level example and is not executable in its current form.
2. The `PlayerLivesAddress` is just an example and may not be the actual address in the NSMBW game's memory. Tools such as Dolphin Emulator's memory viewer/debugger can be used to find the correct addresses.
3. The `WriteToMemory` function would need a proper implementation that can interact with the memory of the running game. This might involve writing a custom memory editing routine or using existing libraries/tools that support memory manipulation.

To actually apply such patches while the game is running on the Wii or an emulator, you would typically generate and apply code through gecko codes or similar systems. Here’s an example of an equivalent gecko code for infinite lives:

```plaintext
# Infinite Lives [Example]
0434E788 00000063
```

This plaintext gecko code doesn’t use C++, but it directly writes the value `0x63` (99 in decimal) to the memory address `0x8034E788`. It uses the syntax typical for the Gecko code system where `04` indicates a 32-bit write.

Creating complex patches might require more sophisticated methods, such as hooking functions or patching executable code sections, which requires in-depth knowledge of the game’s binary and assembly code.

If you are serious about developing custom codes and patches, I recommend:

1. Studying the assembly code and reverse engineering techniques.
2. Using the Dolphin Emulator for testing and debugging.
3. Exploring tools like Wiird and Cheat Engine.

Always remember that modifying game code should be done respectfully. In a competitive or online scenario, make sure you abide by the community guidelines and terms of service.
