Our verdict on Lunar IPS
Lunar IPS is a free Windows utility for creating and applying International Patching System (IPS) patches to ROM files. It fits users who work specifically with IPS and want a focused desktop tool rather than a broader patch-format suite. The published requirements include 32-bit and 64-bit Windows support, while the utility handles files up to 16 MB.
Its feature set covers the core IPS workflow and several useful file operations. Users can create and apply IPS patches, use RLE encoding and decoding, expand or truncate files, and register IPS files with Windows. Patch application logging adds a record of patch activity, and command-line options provide a way to incorporate the utility into scripted workflows. With a free pricing model and a free plan, Lunar IPS is straightforward to consider for personal ROM patching where IPS is the required format.
The main trade-off is its narrow scope. Lunar IPS is limited to IPS, so users working across multiple patch formats should choose a tool designed for broader format coverage. It is also limited to Windows, which excludes users on other platforms, and its 16 MB file limit constrains larger files. Pick Lunar IPS when free IPS creation and application, basic file handling, logging, and command-line access match the task. Choose an alternative when cross-platform availability, multiple patch formats, or support for files above 16 MB is essential.
