He compiled custom code—dubbed an nmk004-trojan —and burned it to the external board space. This code tricked the NMK004 chip into remapping its internal "shared note length table" pointer directly into the protected execution memory segment ($0000–$1400).
For years, the NMK004’s protected ROM was considered un-dumpable using conventional means. The chip’s security design had successfully thwarted attempts by preservationists and hobbyists for nearly 20 years. The breakthrough finally came in 2014 from a hacker known as . nmk004.bin
When the emulation community—led by projects like (Multiple Arcade Machine Emulator)—began archiving NMK arcade boards, they ran into a massive roadblock. While they could easily read the external game ROMs, the internal code masked inside the NMK004 was completely inaccessible. While they could easily read the external game
