Sega controllers?

[XORadmin]

I was doing some tests right now and got the following basic issues with 2 types of controllers:

Original Sega controllers are powered with 5 Volt and provide the controlling with 5 volt levels. All fine, working without any problem for years.

8Bit DO Wireless receiver: Does seem to work well properly when interfaced slower than the original speed. With original speed there seem to be occational 'ghost'- button presses. Also it does funny things with the voltages. While all is on a 5 volt level, it pulls the voltage of the select line down to 2 Volt (it is not suppose to touch it at all since it is a output). Controller lines are replied with 3,3 Volt (which should be 5 volt as well). I got to see how stable it would be in long term running on slower speed.

Retrobit controllers: Seem to work fine in the first place, but some cases reported that it fried suddenly. I just had exactly same issue and ended up in a dead controller. Doing some research and the sudden death of these controllers seem to be a more common issue. (check amazon reviews and more, not related to the nerdSEQ at all but with regular use with a sega console. I can't make any statements about how often this happens, but it does happen)
So I do not recommend the retrobit controllers.

Yes, I am noticing the ghosting as well.  At first I thought it was the new firmware, but I probably didn't use the controller enough prior to the firmware to notice, so correlation not causation there.  Is there anything that can be done on the nerdSEQ side? I don't know what it means to interface slower than the original speed, if that can be a choice for those of us using this wireless receiver.  As much as I love the click of the original buttons, it's great for my ergonomics to have this wireless setup.

I think the ghosting is related to the new firmware. I use there the original speeds and I also found out about that today after your message.
Before I used slower speeds which was fine for the original sega gamepads but the retrobit ones didn't work well with it. I don't remember having ghosting with the 8Bit DO then.

For sure I can define the speed depending on which gamepad is 'selected'. I'm gonna try it out with the 8Bit DO sometime this weekend.
That doesn't take away that it really pulls on the voltages which is not a good thing I think. I will analyse that as well.
