⚡ Range Fill Tool — Cheat Engine Plugin ⚡

Lightweight plugin for Cheat Engine that offers a powerful and efficient way to fill any memory range with a specific value or custom byte pattern.

Instead of editing values one by one manually, this tool allows you to instantly apply repeated data across the entire selected memory region. As a result, it dramatically speeds up your workflow while significantly reducing manual effort. Moreover, it proves especially valuable in reverse engineering, debugging, and game hacking scenarios.

In addition, the plugin supports both typed values and fully custom byte patterns, which gives you exceptional flexibility for almost any use case. Furthermore, thanks to the built-in preview system, you can carefully review all changes before applying them. Therefore, you stay in complete control and easily avoid potential mistakes.

What’s more, support for custom step values unlocks advanced techniques, such as overlapping writes when necessary. Consequently, experienced users gain even more creative possibilities. Finally, the fully DPI-aware interface ensures smooth and consistent usability across different screen resolutions and scaling settings.

🧠 What the Plugin Does 🧠

Range Fill Tool allows you to automatically fill a selected memory range with a repeating value or byte pattern.

For example, instead of manually writing:

00090001 00090001 00090001 …

You can apply it instantly across the entire memory range with one click.

This is especially useful for:

• Filling inventory slots
• Initializing large memory regions
• Testing memory behavior
• Applying repeated structures or values
