VRC7 audio emulator

[Delphi1024]

Hi everyone!

I recently spend a lot of time looking at the vrc7 die photo and started writing an emulator for it. It is written in C, with the aim of being somewhat compatible with emu2413.

All testing was done with NSFPlay and the Lagrange Point nsf. Some songs still sound slightly off compared to the hardware recordings, but most of them are pretty close.

First NukeYKT and now this. It's great to see the VRC7 finally getting some love.

Nice work!

There are a lot of detailed reverse engineering notes on the OPLL which should apply to the VRC7 as well (except the rhythm part) that have been added here recently:
