With the successful dumping of the NMK004's internal ROM, the nmk004.bin file became the essential BIOS for a library of arcade games. In modern emulation, particularly in the (FBNeo) and MAME emulators, this file acts as a master key. It is a standardized piece of hardware emulation that can be shared across dozens of games, rather than having to embed the same code into every individual ROM file.

In "merged" ROM sets, this file is sometimes already included inside the game's zip file to prevent errors. The NMK004 is a proprietary sound processing unit
