The American subsidiary of Japanese video game developer Nintendo recently filed a complaint alleging claims of copyright and trademark infringement as well as unfair competition against an operator of a website offering pirated copies of read-only memory (ROM) files collected from Nintendo cartridges without authorization. The case, filed in the District of Arizona, has already resulted in the successful shutdown of the two websites at issue which have been offering unauthorized ROM files, but it may also be an indication that the video game industry might benefit from the use of a freemium platform such as has been developed in the music and movie industries. As Nintendo's lawsuit notes, ROMs involve a process of copying video game software from a game cartridge or disc and then making copies of those files available online. These ROM files can then be played using an emulator program that runs on a computer or a mobile phone, mimicking the functionality of physical video game console systems.
