(Note that xdelta-1.x used the original format known as xdelta xdelta-3.x uses the standard VCDIFF format.) Another format,, takes shifted data into account, resulting in much smaller patches. Though saxman's RXL patch format was designed to replace IPS, it quickly faded into obscurity along with its predecessor. The massive shifts in the ROM that can result from reassembly made IPS patches very large, and they would often contain a good volume of code anyway, thus eliminating the alleged legal advantage. This format fell out of use when split disassemblies became available as a way to edit game data, and when dial-up was being replaced by faster broadband connections. It was also believed, that since patches do not contain any copyrighted code, it was not illegal to distribute one.

Sonic hacks are altered versions of Sonic the Hedgehog games that have been edited through the process of ROM Hacking.
