Can remembers which ROMs you've used, and use them again if it thinks it's correct (BPS only, GUI only).Can apply multiple patches to the same ROM, creating a huge pile of ROMs (GUI only).Fully-featured GUIs under Windows and GTK+, including command line support can also be a pure command line program.Creates the smallest IPS patches of any known tool in existence, too (but only a little smaller, Lunar IPS is quite good).Creates the smallest BPS patches of any known tool in existence, and is faster than any other comparable creator.
Updates can be found on the repository page (source only). Floating IPS, also known as Flips, is a patcher for IPS and BPS files, aiming for a simple interface yet plenty of power under the hood.
