Breeze

A Nintendo Switch game cheating tool designed to work seamlessly with Atmosphere's cheatVM.

This project started as a rewrite of the features implemented in EdiZon SE. Over time, the code for EdiZon SE became increasingly difficult to maintain, and its UI posed challenges for many users.

Over time, numerous features were added, along with significant optimizations, making Breeze much faster and far more powerful than EdiZone SE

Objectives

1. Improve the User Interface: Ensure more users can access and enjoy the tool’s features.
2. Streamline Codebase: Make the code easier to develop and extend.
3. Leverage Experience: Apply lessons learned from SE tools to create a robust foundation for future development.
4. All in one tool: Every task involved in cheat creations can be perform with Breeze alone on Switch.

Search Concepts

Key Ideas

1. Static Memory Locations: Memory storing relevant data can remain static for a window of time. Searches aim to locate these locations during that window.
2. Game-Specific Conditions: In most cases, critical memory locations remain consistent during specific periods, such as between loading screens. However, some locations are stable only under certain conditions, such as within a specific game mode or screen, and may become invalid once the state changes (e.g., exiting the screen). It is up to the user to infer the conditions under which these memory addresses remain static and attempt to complete the search within that limited window of opportunity.
3. Data Types:
   • Common formats include u32, f32, f64, u16, u8, obfuscated types, and packed integers.
   • Try searching in this order for best results.

Search Strategies

• Known Value Search: Begin with what you see, guessing the data type and searching for visible values.
• Fuzzy Search: Use range searches when values aren't directly represented. For example, search for "3 to 300" for a health bar representing three hearts.
• Full Unknown Search: When all else fails, dump memory and compare changes to refine the results.

Game Hacking Concepts

1. Approaches:
   • Modify game data directly.
   • Alter the game code that modifies the data.
2. Memory Address Value: Some addresses store effective values, while others only display values.
3. ASLR Impact: Address Space Layout Randomization means memory addresses differ between game sessions.
   • Use static addresses relative to main or heap, or employ pointer chains or ASM hacks when necessary.

Breeze Search Manager

• Commands:

  1. memory dump
  2. dump compare
  3. start search
  4. continue search

• File Management:

  • Generated files (.dat) are stored at sdmc:/switch/Breeze/.
  • Files remain valid only within the current memory state window.
  • Manage files manually or let Breeze handle cleanup during new sessions.

• Workflow:

  • Start a search using memory dump or start search.
  • Follow up with dump compare or continue search.
  • Pause searches with Pause Search and resume later.
