JOTEGO

Can you tell the theme?

I have spent a few days bringing my YM2151 core up to some design practices I didn't follow at the time. I have added clock gating, which allows to use a single clock domain for all the FPGA core -this helps synthesis. I have also updated its CPU interface to work better with CPUs that use a different clock enable signal, following the JT12 scheme. I tried not to break the FM synthesis core as that was already proven to be 100% accurate. Yet, I introduced a couple of bugs and had to do some debugging.

In case you don't know this is the chip used for System 16, CPS1, some CPS0 games (such as Bionic Commando), X68000 and many other great games. This is a better FM synthesizer than the one used in NeoGeo but it lacks PCM/ADPCM capabilities.

Listen to the attached song, obtained from simulation. Can you tell which one it is?
