Wrong pinout

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?

"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)[reply]

6 Channels?

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)[reply]

...sorry for the absurd wrong typed words - it seems my free ubuntu app that checks spelling is mighty crap... 93.133.250.173 (talk) 17:33, 16 December 2024 (UTC)[reply]
