Will it (ever) be possible to emulate special chips?

[King Of Chaos]

There's a few versions of the DSP-1 chip (DSP-1, DSP-1A and DSP-1B) and not all DSP-1 boot games work, e.g. my version of Pilotwings. Without opening it, I'm not sure if it's DSP-1 or DSP-1B. Best bet is Super Mario Kart, however chances are not all of those will work either due to the cart using either revision.

The DSP-1 chips are supposedly backwards compatible.

Ballz has the DSP-1B chip. It's also easy to get a hold of.

All three have been decapped and dumped. I have the program ROMs for each.

Interesting enough, depending on the revision of the DSP-1 chip in Pilotwings, you can get a different intro.

An update/bump for those whom care about the dumping of the special chips for the SNES.

The Cx4 program ROM was found to be both Mega Man X2 and Mega Man X3 and the Cx4 data ROM was dumped as well. There's only one special chip left to be dumped/LLE emulated for the SNES, the ST-0018.
