Extensible ROMhack Interchange Format (XRIF)

XRIF is an extensible binary patching format meant to replace IPS. It has a flexible internal structure and features that improve upon what IPS can do, such as a larger address range, embedded annotation, and different ways to approach the patching process.

XRIF itself is a general-purpose format, but it can be Extended to better accomodate special purposes, such as NES patching.

Extensions

XRIF+NES

For patching NES/Famicom cartridge files. This was the first Extension of XRIF, and XRIF was more or less designed as a vehicle for it.

XRIF+SuperNES

For handling Super NES cartridge files; specifically, to work around headering and interlacing issues, but otherwise doesn't add any new functionality to XRIF.
