True... However, the Korean songs are the only songs not included in the Original Soundtrack (I own all the series OST) and is arcade exclusive. Hence I am trying to see if there is a way to get the music off from the arcade data instead... :P
The digital board involves 2 large FPGAs and an MPEG decoder with reprogrammable microcode that can be made to read anything. So we're assuming it's some sort of encrypted or otherwise bitstream-incompatible MPEG-1 audio thing.
Are these FPGAs and MPEG decoder ASIC targets for decapping? Or are there other ways to figure things out? Have there ever been any bootlegs/hacks for DDR digital? (or are the bootlegs all either DDR analog or DDR digital with custom sound boards)
Although I would imagine that proper emulation of these latter DDR games might invite the wrath of Konami :P
The games download a large binary blob at boot. We're not clear if that's FPGA microcode, MPEG decoder microcode, or both, but clearly there's very little ROM involved so decapping probably wouldn't be necessary.
