Individual games were then distributed on separate cartridges or daughterboards that plugged into this master board. Once you install them correctly—ZIPs intact, paths set,
By default, MAME (the command-line version or MAMEUI) uses a folder named roms inside its installation directory. If you use a frontend like QMC2 or LaunchBox, you may have set a custom path.
If you try to run a game like Metal Slug without its corresponding Neo Geo BIOS, MAME will immediately throw an error and refuse to launch. The game ROM contains the graphics, levels, and logic, but it completely lacks the foundational system code required to actually boot up the hardware platform.
