.GEN File Extension
File Type 1Sega Genesis ROM
What is a GEN file?
Game ROM used by Sega Genesis/Megadrive emulators; saves a copy of the contents of an original game cartridge and allows the game to be played on a PC with supporting emulation software, such as Kega Fusion or Genesis Plus.
The GEN file extension is interchangeable with the .SMD and .BIN file extensions, which are also used for Sega Genesis ROMs. However, since the ".bin" file extension is used for so many different file associations, sometimes the ".smd" and ".gen" extensions are preferred.
