bluejay Posted September 8, 2019 Share Posted September 8, 2019 I've heard that Atari 2600, Sega Genesis, and ColecoVision controllers are all interchangeable, and a certain button on the Genesis controller(the "select" I think?) would fry the atari when pressed. I want to know which button on which controller would represent the fire button on the atari or the c button on the Genesis. Thanks in advance! 1 Quote Link to comment Share on other sites More sharing options...

Well, I get this from taking a look at the wiring: by pressing select on a Genesis pad, you short pins 7 and 8, which are +5V and GND on a 2600. But "select" isn't a button, but a way for the Generis to select which buttons to check. So if I read the table correctly it's Button "B", since select is +5V on the 2600. Button "C" on the Genesis pad is connected to one of the paddles potentiometers. 2600 controller pinout Genesis controller pinout Edited September 8, 2019 by SvOlli Quote Link to comment Share on other sites More sharing options...
fiddlepaddle Posted September 8, 2019 Share Posted September 8, 2019 (edited) I know under some conditions, plugging or unplugging a controller from the colecovision while it's on can blow a chip(s). I wouldn't be surprised if the same effect could occur by pressing buttons on the genesis controller plugged into the colecovision. I haven't heard of, or experienced any damage to a 2600 (or 7800) using a genesis controller, which I have been using routinely for many years. Don't know why you would plug a colecovision controller into an Atari, except maybe just for funzies because it fits, but I wouldn't do it.

sirlynxalot Posted September 13, 2019 Share Posted September 13, 2019 Genesis controllers don't have select buttons. Can confirm the start button doesn't fry an Atari. I've used both the 3 and 6 button genesis controller on 2600s for years with no bad effect. Quote Link to comment Share on other sites More sharing options...
bluejay Posted September 14, 2019 Author Share Posted September 14, 2019 So they basically are all interchangeable? Quote Link to comment Share on other sites More sharing options...
The Usotsuki Posted September 15, 2019 Share Posted September 15, 2019 You can blow a 6526 in the C64 by pressing the wrong button on a Genesis pad, might that be what you're thinking of? Quote Link to comment Share on other sites More sharing options...
