Wrong pinout
[edit]The /OE pin in the pinout diagram is actually a chip enable, and is marked "/CE" in the chip's datasheet.
How did the stereo work?
[edit]"Game Gear's version includes an extension for stereo audio output"
Was this controllable within the chip, meaning that one could (for instance) set channel 1 to be on the left and channel 2 on the right? Or is this simply two outputs of the same sound to (slightly) simplify the downstream electronics? If the first case (which I suspect), were there additional registers to control this?

- I'm not sure on the technical side, but stereo wasn't controlled by the end user, the Game Gear just offered an option to composers to hard-pan the two channels across the speakers. This can be heard by checking out the MS/GG VGM sets for one of the Sonic games (I think Sonic 2). ~ Dissident93 (talk) 19:57, 11 May 2018 (UTC)
6 Channels?
[edit]Howdy! This sound chip is build in the sega sc-3000/sg-1000 comuters/cosoles. Where ever you look, old-computers.com, 8-bit nirvana etc. - every page says, that it has 6 channels for sound output. How does that match with the 4 channels mentioned here? Who is right then? Does anybody know? Thanks a lot - Anne, Germany 93.133.250.173 (talk) 17:30, 16 December 2024 (UTC)
