Mario Compilation -wueruu- |top|

Nintendo is notoriously protective of its IP. In recent years, the company has issued DMCA takedowns against various fan projects. However, ROM hacks and compilations usually survive by distributing rather than the full game files. A patch contains only the code changes , not the original game. To play "Mario Compilation -Wueruu-", a user technically must own a copy of the original Super Mario World ROM to apply the patch.
