All of these features are more or less "impossible" to ever implement in this emulator, in my opinion. for this emulator to handle raw hardware input, you need sub-frame polling with timing synchronized to the framerate, and either some kinda zero-latency display device, or some very advanced kinda frame-rewinding feature that interacts with that sub-frame polling. It needs to change mid-frame at very specific times for the software to work. The game software is based on the complex near-zero-latency stream of info through the TV->gun->$4017. That is just not enough input information to do anything useful with any zapper game. I still don't understand what the second "button" is supposed to represent, though? You can't represent what the zapper's light sensor is doing with an on-off poll through USB.

The NES LCD Mod project you linked is demonstrating it with a Russian clone zapper. There are several clone zappers without such a strong filter. The NES zapper can't work on most LCD screens, though I do think some models with a CF backlight flicker at a high enough frequency to get through its filter. I'm curious what you mean about playing with a real zapper though.

if anything I would just suggest having the sensor position update always and not only when the trigger is pulled, rather than trying to assign it to a button? That's how Mesen handles it, and I think that works very well. I haven't yet run across any older games where it mattered where the zapper was pointed when not pulling the trigger. "ZapPing" from Action 53) or test ROMs ( zapper tests, Zap Ruder). As far as I know this only matters for a small handful of homebrew games (e.g. You can't do anything that involves aiming without pulling the trigger.

so I think the important input is just where the zapper is pointed, a light-or-not button doesn't really map to the hardware concept as it's missing that aspect of timing that comes from the video position.įCEUX's zapper implementation is a little bit annoying because it does not update the light sensor position except when you click the button. The actual window of time where $4017 starts registering the light is a fairly narrow portion of the frame.

The zapper itself filters out light that does not turn on and off at high frequencies, it's basically a "scanline" sensor. What does it mean to play FCEUX with a real zapper?Īs for controlling the light sensor with a separate button, I'm not sure what you would do with that? Actual games that use the zapper require the light sensor to be on and off with sub-frame timing.
