I cannot imagine getting a fingernail stuck?
2 points here:
How can you even bend your thumb to an angle that this could happen?
How long do you go between cutting your nails?
Hmmm, I found the original controllers comfortable and intuitive.
I never used overlays. I liked feeling the bubbled numbers.
I used the pad of my left thumb hovering over the number 5. leaving 2 fingers wrapped around for the side buttons if needed.
And hovered my right thumb over the disc. But always used the pad of my thumbs.
Aaaaahhhhh! Now I know why my friends controllers and overlays were always scratched and ripped.
The controller felt so natural in my hands, I never noticed the RUNNING and Shooting problem in Night Stalker or Deadly Disc until I read about it here.
I guess, I must have noticed it early on and subconsciously let go of the disc for a moment to use the number pad.
So how do people hold the controller? I hold the controller in my left palm, thumb for keypad and fingers for 2 side buttons.
Exceptions. Bump n Jump, I got this when I replaced my Intellivision 1 with an intellivision 2.
I then had my fingers tightly wrapped on the left side of the controller and used my thumb to jump.
Those controllers truly suck and I did alter how I held the controller for the SHOOTING games.
I also had a colecovision, I liked the controller for the most part. I liked the notches in the 8 directions, Good for venture etc.
The Button locations also worked well for my left palm holding the controller. Thumb on left button, pointer on right button (when needed).
I did have a hard time with the number pad though. I could not GLIDE my thumb from number to number so easy.
But to be honest, I only had Mouse trap that used the keypad during game play.
All that said.... Try playing with the Flashback controllers!!!!! Better than the original!
