Can you make me Some Custom code powerups for NSMBW

1 answer

Creating custom code power-ups for "New Super Mario Bros. Wii" (NSMBW) is a complex task that involves understanding the game's internal coding and assembly language, as well as using tools specifically designed for Wii homebrew and modding. Below, I'll give you a broad outline of the steps you might take to implement custom power-ups, but please note that this requires a fair amount of technical expertise and familiarity with Wii homebrew development.

### Tools and Resources You’ll Need:
1. **Wii Homebrew Channel**: To run custom code on your Wii.
2. **Gecko OS**: Useful for applying codes.
3. **Dolphin Emulator**: For testing your modifications on a PC.
4. **Wii Scrubber**: To extract files from the NSMBW ISO.
5. **CodeWright or similar**: Text editor for coding.
6. **An understanding of PowerPC assembly**: Wii games run on a PowerPC CPU, so you'll need to write assembly codes.
7. **Existing NSMBW Documentation and Modding Resources**: Communities like GBATemp and Kuribo64 can be invaluable.

### Step-by-Step Guide:

#### 1. Setting Up Your Environment:
- Install the Homebrew Channel on your Wii if you haven’t already.
- Install Gecko OS to load custom codes.
- Set up your Dolphin Emulator on PC for easier testing.

#### 2. Extracting the Game Files:
- Use Wii Scrubber to open the NSMBW ISO and extract the relevant game files, particularly the ones related to power-ups.

#### 3. Understanding the Game's Code:
- You will need to familiarize yourself with the NSMBW’s internal code. Documentation and scripts from other modders can be a huge help here.
- Tools like Dolphin Debugger can help you step through the code to understand how existing power-ups work.

#### 4. Writing the Custom Code:
- Write your custom power-up code in PowerPC assembly. This can be very complex and assumes you know how to manipulate the game's memory.
- Make small changes incrementally and test frequently.

#### Example: Creating a Double Jump Power-Up
This example will show a very simplified idea. Actual implementation will be much more complex and game-specific.

```assembly
# Example Assembly Code (Highly Simplified)
# Assume R0 holds player structure and R3 holds current jump state.
# Power-up check (This is pseudo-assembly and will not work as-is)

# Check if Player has Double Jump Power-Up
li R4, DOUBLE_JUMP_POWERUP_ID
lwz R5, 0xABC(R0) # Load current power-up into R5 (structure offset might vary)
cmpw R4, R5
bne NoDoubleJump # If not equal, branch to NoDoubleJump

# Allow Double Jump Logic
lwz R6, 0xDEF(R0) # Load current jump state
cmpwi R6, DOUBLE_JUMP_AVAILABLE
beq PerformDoubleJump

NoDoubleJump:
# Default Jump Logic Here
...
PerformDoubleJump:
# Your Double Jump Logic Here
...

```

#### 5. Injecting the Custom Code:
- Use an assembly injector to insert your custom PowerPC code into the NSMBW game.
- Tools like CodeWright can help compile and inject these codes.

#### 6. Testing:
- Always test your changes on an emulator like Dolphin before using them on your actual Wii to avoid soft bricks.
- Debug and refine your code iteratively.

#### 7. Sharing and Documentation:
- Document your changes and share them with the modding community. This helps others learn and can help you get feedback.

### Important Considerations:
- **Legal Issues**: Modding a game you don’t own or distributing modified game ISOs is illegal.
- **Bricking Risk**: Incorrectly modifying system or game files can brick your Wii.
- **Community Guidelines**: Respect the norms and guidelines of the modding community you’re participating in.

### Learning Resources:
- **Assembler and PPC Assembly Tutorials**: Essential for writing your custom code.
- **NSMBW Modding Forums**: Communities like GBATemp and Kuribo64.
- **YouTube Tutorials and Github Repositories**: For practical examples and code snippets.

Creating custom power-ups for NSMBW is a rewarding but challenging process. Make sure to back up your original files and proceed with caution. Happy modding!
