How different is the Adlib and Genesis Soundchip?

Sorry if this is in the wrong thread, but I know the Adlib and Sega Genesis both use Yamaha chips, and to me they sound really similar, but how different are they actually? Like I asked one of my friends who uses furnace a lot and likes Sonic if there could be 1:1 recreations of Sonic songs in s3m, and they said no because it's different and I asked them to elaborate and they said they didn't know enough to tell me how. So like how's it different, and with how much work has been put into Adlib emulation, how much pain would it be for someone to extract out Genesis emulation from OpenMPT too?

The difference between OPL and OPN chips are well-documented and can be looked up easily. The most relevant difference is that the OPN supports more algorithms (i.e. how the operators in each patch are combined with each other), which is the main thing that influences the sonic possibilities of different FM synths (the other being being the available operator waveforms). Additionally the S3M format only supports 2-op patches, further reducing the sonic possibilities.

OpenMPT is not, and never will be, a chip tracker. OPL support exists out of necessity, and emulation of other FM chips will not happen. If you need that, use a VST plugin for emulating a specific chip (ADLplug comes to mind), or use a dedicated chip tracker such as Furnace.
