Original sentence: Nintendo sucks
Edited sentence: Emulators have been used by Nintendo and licensed third party companies as a means to re-release older games.It claims that copyright-like rights in mask works protect its games from the exceptions that United States copyright law otherwise provides for backup copies.Nintendo is known for a "no tolerance" stance against emulation of its video games and consoles, stating that it is the single largest threat to the intellectual rights of video game developers.Nintendo uses the claim that emulators running on personal computers have no use other than to play pirated video games, contested by some who say these emulators have been used to develop and test independently produced "homebrew" software on Nintendo's platforms, and that Nintendo's claims contradict copyright laws, mainly that ROM image copiers are illegal (they actually are legal if used to dump unprotected ROM images on to a user's computer for personal use, per (a)(1) and foreign counterparts) and that emulators are illegal (if they do not use copyrighted BIOS, or use other methods to run the game, they are legal).This stance is largely apocryphal, however; Nintendo remains the only modern console manufacturer which has not sued an emulator manufacturer (the most public example being Sony vs.the bleem company)
