The developer behind the awesome LCDMOD project has just announced a new project that allows you to use a zapper with PC emulators on a flat-screen TV! It requires a patched ROM and a way to interface the zapper to the computer but otherwise works similar to the NES version:
The ROM calculates and auto-calibrates the delay added by both the emulator and flat-panel, shown in the upper-left of the screen at the beginning of the video (5 frames…gasp!). Then it compensates the delay, so each shot should line up almost as accurately as on a CRT.
I’ve personally tested this quite a bit with original hardware and found that as long as you use the right Zapper (the Tomee Zap Gun worked best for me), then it’s accurate enough to still be a great experience! Now that it’s available on a PC, I’m interested to see how far this can be taken and what other emulators and games can support this feature!
