This file is typically used for emulation on PCs or mobile devices, or loaded onto flash carts (like the EverDrive-64) to be played on original hardware. Due to the lack of "anti-piracy" patches and the presence of famous glitches, it remains a cornerstone of the retro gaming and speedrunning communities.

The Legend of Zelda: Ocarina of Time is an action-adventure game that follows Link as he travels through time to save Hyrule from Ganondorf.

For preservationists, the (J) ROM is the "pure" artistic vision.
