Functions

Now supports (same logic with cheats makers updating their codes like AOB):

• Update game cheats to other locales (if they don't rewrite the game code, then yes)
• Search the whole main file for code features
• Update normal ASM codes
• Update code cave codes
• Skip page/pageoff codes
• Recognize branch codes and modify their pointer
• Auto fill cheat bids when saving .txt file

TODO:

• Save modified .NSO file base on cheats
• Updating codes in .rodata or somewhere else (aka. high probability breaking the new game 😰 )

Downloading

Visit out releases page or download the latest version.

Usage

Dump main file from xci/nsp/nsz game/updates

There are lots of excellent works for you to dump the main file, like hactool and NSC_Builder. Please choose anyone you familiar with to dump two main files:

• Old Main File: dump from the game which old cheat runs on
• New main File: dump from the game which you want to update the old cheat to

Load main file and copy cheat codes

Build ID of the old main file will be shown after loading. Please make sure it is the same with the old cheat.

Interactively updating the cheat codes

Logs window has everything you need when updating cheat codes.

• Generate: Generate one code or title
• Skip: Skip one code or title, especially for pointer cheats.
• Undo: Undo the last operation.
• Restart: Restart the whole process.
• Wing Length: Decide how many asm code lines are extracted as code features before and after the target address. Supported input type like array [left_side, right_side] and integer "single_input" are listed below:

• Regenerate: Useful when logs window show "address not found". Please change wing length and regenerate until single hit, or maybe double.
• Debug: Generate a debug folder with procedure files to show you what happend during the whole progress.

Save cheat codes with "SaveCHT" button

Building from Source

Pre-Requisites For Build

• Python 3.9
• Packages in requirements.txt
• upx (if bundling to one file need)
• Spec file for pyinstaller (refer here for more info)

Hints For Pre-Requisites

• Choose any python version lower than 3.9 will unleash the support of Windows 7, but not tested. Please use at your own risk.
• There is a main.spec template in project root directory, please change demanded parameters before use.

Usage For Build

Install Python and upx

• Don't forget to add environment variables.

Download source code

Use any command shell you familar with to install support packages

cd your_source_code_root_dir
py -3.9 -m pip install -r requirements.txt

Run the project

py -3.9 __main__.py

OR build the project

pyinstaller -F -w your_spec_name.spec --upx-dir your_upx_dir

Trouble Shooting

1. Why my new codes doesn't work?

   A: On most cases, they are pointer cheat codes that can be recognized from the logs window. Please update these cheats with EdiZon SE or SE tools.

2. Why my new codes break the game?

   A: Game developer will make a huge change for some specific version of games, like adding new function or improving code efficiency. In these cases, the ASM cheat codes need to be refind.

3. Why this application repeating same title over and over again?

   A: It happened when the application failed to get main file bytes. Here are some major reasons: zero gap in bytes file fail to work in capstone (fixed), nsnsotool command failed (fixed), application folder structure destroyed. Please re-download this application or create an issue.
