A BIOS pack is a collection of .zip files containing the system ROMs for console-like arcade platforms or platforms that required specialized boot firmware. In MAME, these are often considered "parent" or "system" files, which need to be placed in the same /roms folder as your game ROMs.
Many arcade and console titles cannot function independently. They rely on proprietary system BIOS files to boot. If you attempt to launch a game that requires one without having it present, MAME will return an error message or fail to load entirely.

Rather than a collection of full game ROMs, a BIOS pack gathers the essential firmware and system-level images needed to boot and run entire families of arcade hardware. The 0.238 pack, matching MAME version 0.238, acts as a foundation — the DNA — that lets many individual titles run correctly under the emulator.
In the context of emulation, a BIOS (Basic Input/Output System) file is the firmware from the original arcade hardware. Unlike modern PCs, many arcade systems required specialized software to initialize the hardware before the game code could load.
