How to Add 20XX Training Mod to Melee on Wii

Whether you’re an aspiring competitive Super Smash Bros. Melee player or simply a fan of the game wanting to polish your skills, the 20XX Training Mod is a goldmine of utilities and features designed to push your gameplay to the next level. Aptly named after the idea that “in the year 20XX, every Melee player will play like a top-level Fox,” this mod transforms your standard Melee experience into an intensive training lab. Installing it on your Wii may seem daunting, but with the right steps, it’s surprisingly doable.

TL;DR (Too Long; Didn’t Read)

The 20XX Training Mod is a custom version of Super Smash Bros. Melee designed to help players train and improve. To use it on your Wii, you’ll need a homebrewed system, a Melee ISO, a 20XX build, and a method to run GameCube games from an SD card. Once installed, you’ll have access to advanced training features such as CPU DI control, infinite shield, hitbox visualization, and more. With a bit of setup, you’ll be practicing like the pros in no time.

What Is the 20XX Training Mod?

The 20XX Training Mod is a customized version of Super Smash Bros. Melee that adds a range of tools and hacks to improve your technical skills. It has become a staple in the competitive Melee community because it allows players to:

• Practice techniques like wavedashing and L-canceling more efficiently
• Use save states and frame advance for frame-by-frame analysis
• Visualize hitboxes and hurtboxes
• Customize CPU behavior like DI, teching, and shield options

In short, 20XX is like having a personal coach in your system, fine-tuned for hardcore practice and labbing.

What You’ll Need

Before you get started, you’ll need a few key items and tools:

• A Nintendo Wii (preferably one with GameCube controller ports)
• A homebrewed Wii with support for running GameCube backups (via Nintendont or similar)
• A Super Smash Bros. Melee ISO (NTSC version highly recommended)
• The 20XX Training Mod ISO or patcher
• An SD card (at least 2GB, formatted to FAT32)
• A way to launch GameCube games from your SD card (USB Loader GX or Homebrew Channel with Nintendont)

Step-by-Step: Installing 20XX on Wii

Step 1: Homebrew Your Wii

If you haven’t already homebrewed your Wii, this is the first step. You can do this using the LetterBomb method for Wii System Menu 4.3 or other exploit-based methods for earlier versions. Homebrewing gives you access to third-party apps through the Homebrew Channel.

Here’s a brief overview:

1. Find your Wii’s system version in Wii Settings.
2. Visit please.hackmii.com, input your Wii’s MAC Address, and generate a LetterBomb package.
3. Transfer the contents to your SD card and insert it into your Wii.
4. Open the Wii Message Board, look for the LetterBomb message, and run the installer.

Step 2: Install Nintendont

Nintendont is the most reliable way to run GameCube backups on a Wii. You can install this directly via the Homebrew Browser or download it manually and put it on your SD card in the /apps/nintendont/ directory.

Once installed, Nintendont lets you launch GameCube games from an SD card or USB drive. It’s crucial for running the 20XX ISO.

Step 3: Obtain a Melee ISO and 20XX

You’ll need an NTSC (North American) ISO of Super Smash Bros. Melee. Due to legal restrictions, we can’t link to or provide ISOs, so ensure you back up your own physical copy if necessary.

Next, download the latest version of the 20XX Training Mod. You have two options:

• A fully patched ISO version of 20XX (easiest if you have the space and want plug-and-play access)
• A patch program (like xdelta) that converts your Melee ISO into a 20XX build

If you go the patching route:

1. Download the 20XX xdelta patch and the patching tool
2. Apply the patch to your Melee ISO using xdeltaUI or a similar program
3. Rename the patched ISO to something like game.iso

Step 4: Place the ISO on Your SD Card

Create a folder called /games/SSBM on your SD card. Inside this folder, place your patched 20XX ISO and name it game.iso. It should look like this:

SD:/games/SSBM/game.iso

This is the folder structure recognized by Nintendont when loading GameCube games from an SD card.

Step 5: Load Nintendont and Launch 20XX

Insert the SD card into your Wii, load the Homebrew Channel, and open Nintendont. Navigate to your list of games, select the 20XX ISO, and press Start.

Within seconds, you should boot directly into the 20XX Training Mod. From here, you can explore the tool-rich menu system by pressing D-Pad Down on the character select screen to open the in-game debug menu.

Notable Features of 20XX

Some of the standout features include:

• Visual Debugging: View hitboxes, hurtboxes, invincibility and more in real-time
• CPU AI Tweaks: Set CPU DI, tech directions, shielding frequency, and even scripted behaviors
• Stage Modifiers: Turn off stage hazards or use alternate levels for training
• Frame Data Tools: Use frame advance, play/pause mechanics, and input displays to analyze intricate timings
• Save States: Create checkpoints to quickly repeat a scenario and practice it perfectly

Tips for Optimizing Your Training

To make the most of 20XX on your Wii, follow these tips:

• Keep a notebook or app for tracking your progress and goals
• Focus on one technique at a time (e.g., short-hop aerials or shield dropping)
• Use save states to practice tech chases and punish options repetitively
• Set CPUs to behave in specific ways using the debug menu—for example, always DI out or always shield—so you can practice punishments reliably
• Experiment! Try unusual characters or stages to discover new movement options

Potential Issues and How to Fix Them

If you encounter problems, here are some common issues and fixes:

• Nintendont Error: Make sure your SD card is formatted to FAT32 and your folder structure is correct
• ISO Not Showing: Check that your ISO is inside /games/SSBM/ and named game.iso
• Controller Input Lag: Use a wired GameCube controller; avoid third-party variants if possible
• Menu Not Working: Remember to press D-Pad Down on the character select screen to activate the debug menu

Conclusion

Adding the 20XX Training Mod to your Wii is one of the best moves you can make as a Melee player. While there are a few setup steps involved—like homebrewing your system and running Nintendont—the payoff is significant. You’ll gain access to a trove of training tools that elite players use to power up their gameplay. Whether you’re combo testing, tech chasing, or just fine-tuning your movement, 20XX is the dojo you’ve been looking for.
