To avoid copyright issues, some people distribute their changes as “patch” files that contain only the changes made to the ROM, not any of the original ROM data.

Here are some programs to patch ROMs with these files.

Windows

Use Lunar IPS.

Mac OS X, BSD, Linux

For a graphical interface, try Lazy IPS.

For a command‐line program, try uips from Neill Corlett’s cmdpack.
