Thomas Harte	84b115f15f	Attempts to move forward in defining what the parts of an OPL are meant to do.	2020-04-10 19:13:52 -04:00
Thomas Harte	a0d14f4030	Starts trying to make sense of the various fields at play.	2020-04-08 23:15:44 -04:00
Thomas Harte	dd6769bfbc	Splits OPLL and OPL2 classes. ... Logic is: they have different mixers (additive in the OPL2, time-division multiplexing in the OPLL) as well as different register sets. So I'll put operator and channel logic directly into those structs.	2020-04-07 23:15:26 -04:00
Thomas Harte	db4b71fc9a	Adds correct LSFR, something of OPLL -> OPL2 logic.	2020-04-05 22:57:53 -04:00
Thomas Harte	0ed7d257e1	Add some extra notes, implement correct mapping to only 18 operators. Not 22.	2020-04-05 14:32:55 -04:00
Thomas Harte	335a68396f	Attempts to complete OPL2 register decoding.	2020-04-04 23:39:09 -04:00
Thomas Harte	84cdf6130f	Starts at least trying to decode OPL2 register writes.	2020-04-04 23:29:25 -04:00
Thomas Harte	b0abc4f7bb	Implements enough wiring that the Master System will instantiate and talk to an OPLL.	2020-04-03 20:05:36 -04:00
