Hi,

I am curious if those Dance Dance Revolution arcade musics can be played in M1/ will be supported in M1? I am particularly looking for the korean version of the DDR 3rd Mix...

Thanks for answering.

Best Regards,

Unfortunately the DDR 3rd Mix and later (the "573 Digital" board) use music compressed/encrypted in an unknown way. Soundtrack CDs for DDR games are generally easy to track down though.

And will likely be higher-quality rips than whatever compression Konami used in the games themselves.

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

You're making me curious. You wouldn't like me when I'm curious.

Ehh, you're right. Doesn't look like Sony's ADPCM in any way. frown

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.

Oh man, people have hacked the crap out of DDR digital machines. ...They've just added new game modes and stuff, not new songs. laugh
