A digital file containing the complete data of the Pokmon HeartGold game, originally released for the Nintendo DS, is commonly referred to as a ROM. These files allow individuals to play the game on emulators, software that mimics the functionality of the original Nintendo DS hardware on other platforms like computers or smartphones. Obtaining these files typically involves extracting the game data from a legitimate cartridge or acquiring it from online sources.
The availability of these files has significantly impacted the preservation and accessibility of the game. Emulation provides a means to experience classic games on modern devices, circumventing the limitations of aging hardware. This access also allows for fan modifications, such as enhanced graphics, adjusted gameplay mechanics, and translations, extending the lifespan and appeal of the original game. However, the distribution and use of these files often raise legal and ethical concerns related to copyright infringement.
