Starting a ROM
Open the emulator program. Depending on the emulator itself, it may have been an installed or a downloaded program. If installed, it can be found under the Start menu, listed alphabetically by name. If downloaded, open the folder it was downloaded to and double click on it.
Click the File tab once the emulator opens up. On the menu that drops down, select the option to open the ROM. Depending on the emulator, the option may be worded as "Start ROM" or "Open ROM."
On the file explorer box that opens, navigate through the files and folders to the location of the desired ROM. Once at the file's location, click on it, and click the OK button in the lower right corner of the box. The emulator will automatically begin running the selected ROM.
