The phrase refers to obtaining and playing the classic Nintendo game “Super Mario Bros.” using a ROM (Read-Only Memory) file on an Android device. A ROM is essentially a digital copy of the game cartridge, and playing it on Android requires an emulator, which is software that mimics the hardware of the original Nintendo Entertainment System (NES). For example, a user might download a “Super Mario Bros.” ROM file from a website and then use an emulator application on their Android phone to play the game.
This practice offers the convenience of playing a beloved retro game on a modern, portable device. It allows individuals to relive nostalgic experiences or discover classic games for the first time. Historically, emulation and ROM use have provided a means of preserving and accessing video games that might otherwise be difficult to obtain or play on their original hardware.
