IPS Files

Jnes

Jnes User Manual
International Patching System

Jnes has the ability to apply IPS files if they are present when loading a rom image automatically.

IPS files are commonly used to translate a game to another language, or more generally alter the games content such as graphics, program code, etc. To use this feature simply make sure the IPS file is in the same directory as the rom you are about to load, and make sure the IPS file is the same name as the rom image.

Example: if you wished to apply an IPS file to "Megaman 2 (U).nes" your patch should be in the same directory named "Megaman 2 (U).IPS".

This is a convenient feature so you can ...

  • maintain the original rom image
  • use the latest patches easily
  • save some disk space?

In the settings dialog there is an option that will make Jnes ask you before applying any patches it finds, or doing it without asking. See the dialog for more information. If you want some patches, visit the message board and links sections of the Jnes website.
