A simple frontend for xdelta. Allows you to easily create and apply xdelta patches without messing with the command-line.
Note that xdelta can account for shifted data, so moving portions of rom around won’t result in patches containing copyrighted data.
Update 1.1 (30.05.09): xdelta UI can now be associated with filetypes for easier use. The recommended ending for xdelta patches is *.xdelta.
