I don't know if this has been brought up before in this thread... (sorry, I've
not read the whole thread - only saw it because it came up in "Active topics")
One CRT specific thing that I doubt could be emulated (without a LOT of
processing power and very specific pixel control)... Is:
CRT scanning. This is important with some old video game systems that had
peripherals that looked at the screen and used the scanning "flicker" to
detect objects positioned on it.
Two things that come to mind are both NES - one is the "light gun", a pistol
you pointed at the screen which used a detector focused on a small area - when
you pulled the trigger, the screen would (almost imperceptibly fast) blank, a draw
a box at the position of the object you wanted to hit - during this time it
would look for the scanning frequency being received by the gun)
eg: "duck hunt" used this to detect if you were aimed a the duck which
would then "get shot"
And even more annoying one was the Nintendo Robot which used screen flicker
to communicate to the robot. I've never gotten these to work on an LCD.
