Quoted from ritewhereiwant2b:The first all LED game I saw was The Wizard of Oz. It looked cold and overdone in IMO, but it was new and I was not used to it. Anyone know if they used warm or none-ghosting LED's?
Probably not. They probably have a proper design, i.e. a design which is suitable for LEDs.
The reason for applying non-ghosting LEDs (or flicker-free for that matter) is because you put in a LED where the game is designed for an incandescent bulb. Since a LED is a different component that doesn't always work. Ghosting happens because the lampmatrix is designed for a bulb. LEDs are faster and show a glow where that is invisible for a bulb. Same for flickering: a bulb has a glowing time, which a LED does not have.
JJP probably has a different design where the game just controls the LEDs the way they should be controlled.
I once read about a mod where a small processor pcb (Arduino/Raspberry or something like it) was controlling the lamps/LEDs in a proper way. It connects to the lampmatrix connectors of a WPC and then controls the lampmatrix itself. Can't find the link.
