ROMs, or Read-Only Memory, refer to the data that makes up a video game. In the context of retro gaming, ROMs are the files that contain the game data, such as graphics, soundtracks, and gameplay mechanics. ROMs are typically extracted from original game cartridges or CDs and are then used in emulators to play the games.
Historically, users acquired ROMs through massive "Fullsets" (complete collections of every game for a specific console). However, the modern trend has moved toward and "Best-Of" packs . retropie roms pack updated
