I'm super impressed that someone has emulated the CZ-101's sound generation LSI!

Lots of people use MAME as an emulator to help reverse-engineering vintage synthesisers. I only recently discovered this too. Since most 80s synths were built mostly out of 'off the shelf' components, it's not too difficult to build a MAME driver which is capable of running the synth's firmware. The actual sound generation is another story though.

I wrote a MAME driver for the Yamaha DX9 while working on this project: https://github.com/ajxs/yamaha_dx97

I wrote a little bit about the project here in case anyone is interested: https://ajxs.me/blog/Hacking_the_Yamaha_DX9_To_Turn_It_Into_...
