Wow, SCC with samples, it's an strange feeling but nice to listen genuine SCC Konami chiptunes again from same MSX composers, it's like back to the past, very recommended . Thank you for sharing that link Grauw.
Hexion does have a K051649 SCC soundchip. But that is an odd board since there is no jamma connector. Hexion is such a late games so it should have one. But I can't find any pictures of the Hexion PCB so am unsure...
It would be so cool to have one of these Konami boards! But probably Mame will have to do. Or perhaps FPGA? I know some Z80-based arcade boards are modeled in FPGA but I don't know if any of Konami's.
