Lunar IPS: Free IPS Patching Tool for ROM Files

Apply IPS patches to update old game ROMs with fan-created fixes, translations, and features in the retrogaming community.

What is Lunar IPS?

Lunar IPS is a free, open-source program used for applying IPS (Incremental Patching System) patches to ROM files, typically retro video game ROMs. It provides a graphical interface that allows users to easily select a clean, unmodified ROM file and the corresponding IPS patch file to apply fixes, translations, or enhancements to the ROM.

Some key features of Lunar IPS include:

• Supports IPS patch files up to 2GB in size
• Patch preview feature shows which bytes will be modified
• Automatically backs up original ROM before patching
• Save patched ROMs with custom filenames
• Cross-platform - works on Windows, Mac, and Linux

Lunar IPS is commonly used by fan translators and ROM hackers in the retrogaming community. Fan translations of Japanese games often distribute translation patches in IPS format to update the text or dialogue. And ROM hacks that fix bugs, rebalance difficulty, expand content, or overhaul graphics in older games also utilize IPS patches and Lunar IPS to distribute those enhancements.

The program provides a simple way for retrogamers to update their collections of classic video game ROMs with community-made patches without needing to know how to code or hex edit files themselves. The intuitive UI and small size of Lunar IPS has led to its widespread adoption for patching ROMs.
