Today I release the verilog source of JT51
, my YM2151 core. You can find it here
I hope this helps bring more systems into the scene, particularly arcade games.
As a result of this development experience, I think I can do other FM synthesizers rather easily. Depending on the results of the poll on future systems which is running at the moment, I will decide which other Yamaha chips to replicate as verilog cores.
I know most people cannot do anything straight away with this, but hopefully this will get some developers moving towards full systems that we will all enjoy.
