Prequisite Reading

• Protecting and Cracking Game Save files
• Hint: All Wii save files have standardized encryption. After decryption using tachtig from Segher Wii Tools, Wii Sports Resort uses binary.
• Articles about my experience with this repository Article 1 / Article 2

Prequisite Hadware/Software

• Wii Sports Resort Save Data - if you have played Wii Sports Resort on your wii, you have this
• SD Card
• Wii that has an SD Card slot - not a Wii Mini
• Laptop or laptop extension that has an SD Card slot
• Terminal that runs BASH 5 or later (On Windows, WSL may be needed.)
• gcc, xxd, git

About

• Retrieve high scores, dates of received stamps, and the last 25 plays from the save file for Wii Sports Resort.

Instructions

Retrieving Save File

• For Wii, open the white slot under the reset button and insert an SD Card.
• From the Home Screen on the Wii, click Wii (bottom left) > Data Managment > Save Data > Wii > Choose Game (Umbrella) > Copy

Deleting a save file will reset the game and remove all scores and progress. Do not click delete.

The save file is stored in SD://private/wii/title/RZTE/data.bin. If there is a file already there, change the folder or file name on your laptop to allow for a newer save file to be copied.

Dowload Wii Segher Tools for Tachtig (and more)

• Type in your terminal: cd ~ then git clone https://github.com/Plombo/segher-wii-tools
• Type in your terminal: cd segher-wii-tools, then type make all. If there are problems, type make clean then make all.
• Typechmod +x tachtig to create an executable file
• Copy the tachtig file to a location in your $PATH with sudo cp tachtig /usr/local/bin You must do this

Transferring the Save File

• Insert the SD Card into a laptop or laptop extension and navigate to SD Card folder
• Rename the private folder to today's date and time 202109071319 for easy tracking of multiple save files.
• If using WSL or if you would like, copy or move the directory to your laptop and outside the SD Card (like your desktop).
• If using WSL, do this mv /mnt/C/users/aaron/Desktop/202109071319 ~/wii-inspect <- Change aaron to your username and make other changes as needed

Using wii-inspect

• Type in your terminal: cd ~ then git clone https://github.com/Aaron98990/wii-inspect
• In the terminal, cd wii-inspect then type bash stamps.bash 202109071319/wii/title/RZTE/data.bin and bash highScores.bash 202109071319/wii/title/RZTE/data.bin <- Change the date and make other changes as needed
• That's all! Enjoy going through history! **Please report any errors (including in README.md) using GitHub's issue function. **

Extra Information

In the Future?

• View high scores on a per-player bases. I know where it is on the data/game file, I just have not "coded" it.
• Extend stamps to more than three players. Don't show stamps screen for no/empty player.
• Improve formatting and use more for loops. Hard to use for loops, especially when lots of switching between hexadecimal, binary, and decimal.
• Paper or Documentation with analysis of offsets of save data
• In Return Table Tennis, the score freezes at 999 but the game continues. I am curious if the save data continues.
• Investigating the recommendation system for Wii Sports Resort. I suspect there is a place to keep track of the number of games played but still testing. Note: playing the game once does not necesairly change the recommended game even after restarting.
• Level (0 - 2500) and accomplishments (Superstar or Pro) for games have not been found but I suspect a place.
• Island Flyover Statistics including iPoints, balloons, 8 unlockable achievments, and balloons/iPoints in 5 minutes record.
• Include the Superstar Score - the score of a game where a player starts and ends at or as close as possible to Skill Level 2000.

Branches

• Everything is done directly to master. Dev is for my experimentations and will include wacky numbers and be harder to read.
