Channel 3 split mode. Turns channel 3 from a single channel of 4 operators into 4 channels of single-operators, or two channels of two-operators.

It does have 6. The YM2612 has the ability to split channel 3 into each individual FM operator. You can use channel 3 to increase the polyphony at the cost of sound complexity, or even use it to make a single sound even more complex. I usually choose to split it into a 2op-2op configuration like here, but occasionally I'll split it into 2op-1op-1op or some other such thing.

@@ChiptunedRaijin I never knew a single Mega Drive game could do this. I only knew about street fighter 2, makind dual PCM if I'm not wrong... Thanks for the info...

@@RetroGames4K A few games do use this special channel 3 mode. Yuzo Koshiro used it for sound effects in Streets of Rage games. Hitoshi Sakimoto used it for music in a few tracks for some games. It was used way more often in PC-88 and PC-98 games, since those Yamaha sound chips share the same ability to use channel 3 in this way.

@@ChiptunedRaijinYeah there is an FM chip with just 3 channels but this ability. Really useful to get more out of a simple chip.

In case you were not aware, the original track is from the SNES version of Waterworld, composed by one of the all time greats to compose for that particular console, Dean Evans.
