Impressive YM2413/OPLL (SMS/MK3, ARC, MSX) Music
While the chip doesn't normally have stereo support, some YT uploads are in stereo (probably via emulation; some vgm player plugins will automatically pan the channels) and some of the audio expansion packs for the MSX provide a kind of stereo effect by playing each chip through only one speaker.
The SMS's PSG and FM chips were only ever combined in the Mark III BIOS screen (Space Harrier theme). I'm not sure why.
The MSX2 used it as an optional addon called the FM-Pac.
