I found out this week the correct way of calculating FM feedback combining the information Sauraen got from inspecting the die and the data I had collected from YM2151. Now I can make an operator without hacks. By hacks I mean that in JT51 I had to write some nasty verilog lines to fit the output to the original. JT12 is going to have a much cleaner implementation, with a smaller area footprint.
I think I will have the operator fully working with FM feedback during this coming week. That is the second milestone.
-FM feedback in operator and channel accumulator
-Register interface and timers
-PCM output and noise
It will probably take about a week to complete each one of them as I have to work on this on my spare time. Bear with me.
