Conclusion
The process of creating this file involved "ROM dumping," where researchers used logic analyzers to capture signals from original arcade boards like Thunder Dragon The "nmk004
The screen didn't show the title menu. Instead, it showed a series of scrolling coordinates and dates—all from the seaside town where he’d found the machine. For a split second, a face appeared in the pixelated static: a young man wearing an arcade technician’s vest, smiling, before the screen finally snapped to the familiar blue logo of NMK.

The file nmk004.bin is a critical device file, or "internal ROM," used by various arcade games developed by the NMK Corporation during the 1990s. It contains data for the NMK004 sound chip, which served as a robust protection mechanism that was notoriously difficult for early bootleggers to crack. Role in Emulation
