In modern arcade emulation, nmk004.bin is treated as a . Rather than being packed inside individual game ROMs, it is stored in a centralized file called nmk004.zip .

Instead of using destructive physical decapping—which involves using acid to expose the silicon die—[trap15] discovered a software exploit. By creating custom code injections (known as "Trojan ROMs") through the unprotected external memory bus, they tricked the chip into treating its own protected internal instruction set as standard sound data. The arcade board essentially "played" its internal code out of the audio jack as raw waveforms.
