@raspberry79 I know I shouldn’t be responding because everyone else has answered you, but I feel need to simplify cause you seem lost.
A file extension, be it a .bin, .iso, .zip, .whatever does not tell you what emulator to use. You have to know what system the game you have is for and put that file(s) into the proper rom folder. That’s it
If you don’t know what systems it is for, we don’t know.
