How to Add BIOS Files to MAME
The Multiple Arcade Machine Emulator (MAME) emulates arcade video games on your computer. Some of the video games supported by MAME require the basic input/output system (BIOS) file used to run the game. Most of the games that need a BIOS file are for specific systems supported by MAME, such as Neo Geo. The BIOS files are placed in the same location as your game files.
Open "Computer" on your computer and double-click the "C" drive.
Double-click "MAME." You may find that the folder has a different name, such as "MAME32." MAME comes in several builds. The build you installed on your computer determines the name of the folder. No matter which build you installed, the word "MAME" is incorporated into the name of the folder.
Open the "Roms" folder.
Right-click the BIOS and select "Copy."
Right-click within the "Roms" folder and select "Paste." The BIOS file is copied to the folder.
Start MAME on your computer. The BIOS file is automatically added to the software.
