Did maybe someone try a MCU implementation of the MAME library or to reverse engineer the hardware using a FPGA before? Similar stuff has been done in the past for the YM2610.
I don't know. Actually i would say almost definitely no for this chip in particular, but of course it is possible. But why use an FPGA when you can do the same with an MCU. All you'll need is a lot of RAM for the samples and enough processing power to mix the samples. This chip doesn't even have any fancy effects, it's just a very basic PCM player (with a low sample rate too, 20khz on real hardware, that's also another reason not to use an actual C140)
