1. Install the Homebrew Channel on your Wii/Wii U. (If you already have the Homebrew Channel installed, you can skip this step.) If you are using a Wii, follow this guide, and if you're using a Wii U, follow this guide. Once it's installed, the Homebrew Channel will allow you to run custom software from an SD card on your Wii or Wii U.
2. Install Riivolution on your Wii/Wii U. (If you already have Riivolution installed, you can skip this step.) Riivolution is a piece of homebrew software that allows you to apply patches to your Wii games. You can get it here.
3. Download the ZIP file linked above.
4. Extract the contents of the downloaded ZIP file. Go into the "tanks-practice-mod" folder, and then copy the "riivolution" and "wiiplay" folders to the root of your SD card. If you are asked if you want to merge folders or replace files, choose "Yes".
5. Once the files finish copying, put the SD card into your Wii or Wii U, insert your Wii Play disc, start the Homebrew Channel, and then start Riivolution from there. If everything works correctly, after a few moments, it should display a menu with the togglable option "Tanks Practice Mod". Enable it, then click Launch to start up the mod.
6. Congratulations! If you did everything right you should be in the mod. Note that to combat version differences, this mod runs a patch that launches the US v1.1 version. If you normally play on a different region, this unfortunately will create a second save file alongside your regular one, but you can just do an NG run or something idk
Ok fine here's how the mod actually works. Currently, this is a mission selector. That's all it is. In the future, I may need to think about creating a layout/color selector too, but that'll be much harder to implement. But anyway, the core use process of this mod is that you have to press "Start over" while holding a certain button combination to change the mission counter by a desired value. The button functions are as follows:
- A: +50
- B: +20
- 1: +10
- 2: +5
- Up: +1
- Left: +2
- Down: +3
- Right: +4
- Minus: Subtract
You can hold any combination of these buttons to add the numbers up to anything you want, and that sum will then be added to the current mission number (or subtracted from it if you're also holding the minus button). This should be pretty straightforward I think. Have fun!
