What is the difference between ROMs, ISOs and emulators?

If you're interested in retro gaming , you've probably come across the terms ROM , ISO , and emulator . These terms are commonly used when talking about playing old video games on modern devices. However, they refer to very different things. Here's a clear guide to understanding this vocabulary and choosing the best solution to relive your favorite games without the hassle .

1. What is an emulator?

An emulator is a software program (or part of the system in a retro console emulator) that mimics the operation of an old game console, such as the NES , GameBoy , PS1 , or Nintendo 64 .

🔁 It allows you to run old games (ROMs or ISOs) on modern hardware such as a PC, an emulator console, or a smartphone.

Examples of popular emulators:

  • RetroArch (multi-console)
  • PPSSPP (PSP)
  • Dolphin (GameCube/Wii)
  • mGBA (GameBoy Advance)

2. What is a ROM?

A ROM is a digital file containing the data of a video game from an original cartridge (like on NES, SNES, GameBoy, etc.).

🔸 The word "ROM" comes from "Read-Only Memory".
🔸 We're talking about ROMs for cartridge console games.

Examples of ROMs:

  • Pokemon_Rouge.gba (GameBoy Advance)
  • Zelda_LinkToThePast.sfc (Super Nintendo)

3. What is an ISO?

An ISO is an image file of a disc , typically used for games released on CD or DVD such as the PlayStation 1 , PlayStation 2 , or GameCube .

🔸 This is an exact copy of the contents of the disc.
🔸 ISOs can be read by CD/DVD compatible emulators.

Examples of ISOs:

  • Final_Fantasy_VII.iso (PS1)
  • DragonBall_Budokai3.iso (PS2)
