I read somewhere about Yamaha YM2151 (OPM) and brother Yamaha YM2164 (OPP) regarding timer B, for instance here . Maybe it is matter of re-checking whichever of these two behaviours should be implemented.
Attempted a fix in the MAME copy of this library to see if it lines up better: https://github.com/mamedev/mame/pull/8988 WIll wait on feedback there before including it in ymfm.
Ok, fix in the MAME side seems to indicate it is working. Commit bb59eb042d6455dc6de31bfa01e7f2e50df2eb94 should take care of it here.
Not sure where to put this, but there were some comments on Mametesters regarding slow music in some Konami games, and how the FPGA implementations dealt with that.
