SMS/GG clock support

[qufb]

I was considering dumping a Game Gear cart that uses the clock pin (e.g. any 1MB ROM with mapper chip 315-5912). Does the Sega Master System/Game Gear module output a clock signal to this pin?

On SMS schematic, slot pin 47 is connected to SI5351 CLK0. This doesn't match what's documented on pinout spreadsheet, which instead assigns SMS/GG clock pin to D16/PH1. However, the module itself doesn't appear to use clockgen. Neither do I see PH1 being used (don't know if it could be controlled to output 3.5MHz pulses). I was expecting some setup similar to N64 EEPROM clock, or maybe pulse_clock() like in Mega Drive module.

So I went back and realized the clock pin is also not connected on these carts... They can be dumped fine, as long as CE(PL1) and A15/M0-7(PH3) are not joined by adaptors, since these are actually distinct outputs, unlike the other 32k-512k carts.

Maybe the story is a bit different with Codemaster carts... but my initial question is answered.
