Light Gun Games Still Work on a Modern TV — Here’s Exactly How

Yes. You can play light gun games on the flat panel you already own. Three routes actually work: a border-tracking gun (Sinden, from $147.00 SGD), a camera/IR gun you assemble yourself (roughly $80–150 in parts), or emulation with a remapped gun (free, but fiddly). The least-effort kit that ships with games included is a G’AIM’E, from $99.99. Nearly everything that goes wrong is calibration, the border, or the emulator’s button map — rarely the gun itself. Below: what each route costs, the settings and version numbers that matter, and the points where the community genuinely disagrees.

Why your Zapper, GunCon, or Menacer is dead

A CRT light gun works by timing. The TV draws the picture with a scanning electron beam, and the gun’s sensor measures the delay between the screen flash and the beam’s known position. A flat panel paints the whole frame at once, so there is no beam to time and the gun gets nothing usable. This is not a driver problem, and no adapter fixes it. The only ways around it are to give the gun something to see — a border, or IR points — or to emulate.

Route 1: border-tracking (Sinden)

The gun watches a white border the software draws around the game window. Official prices, checked 2026-10-08: $147.00 SGD base, $233.00 SGD with recoil, $276.00 SGD for a two-pack, $449.00 SGD for a two-pack with recoil. Ships within two weeks; 7–10 days to North America; no returns.

The border is mandatory every session, not a one-time setup step. The settings that make tracking reliable: contrast 60, brightness 120, exposure −7 to −9, and anti-jitter OFF — leaving anti-jitter on is a common cause of a drifting crosshair. Multi-monitor: the X-ratio is the target monitor’s width divided by the total horizontal span, e.g. 1920 ÷ 5120 = 0.375. On USB, disable selective suspend for the gun’s root hub, or it drops out after idling. Nearby Bluetooth devices interfere. On a Raspberry Pi 4, tracking is fixed by driver v1.08 plus the “use old v1.3 firmware” option — note that this combination cancels recoil.

Route 2: DIY camera/IR (Gun4IR)

The licence is €20.00, reduced from €30.00. A typical build: a DFRobot camera about $24; a Guncon NPC-103 as the donor shell, $20–50; an Arduino Pro Micro $26 for a four-pack; about $20 for the project kit. That lands at $80–150 total. One builder reports finishing in under 30 minutes; treat that as a best case.

Route 3: commercial IR (G’AIM’E)

Basic $99.99, Premium $149.99, Ultimate $199.99 USD. Extra gun $69.99, pedal $29.99. Bandai Namco licensed, and it bundles Time Crisis, Point Blank, and Steel Gunner 1 & 2.

Calibration gotcha: calibrating on a 4:3 image that isn’t filling the screen gives poor accuracy. Stretch the image to fill the display first, then calibrate. One report has accuracy rising from roughly 30% to 55% after doing this — a single report, not a benchmark.

Emulator details that trip people up

MAME changed the light-gun map around version 0.245: the on-screen trigger is now B1 and the off-screen trigger is now B2, where it used to be B0 and B1. If your gun “stopped working” after an update, that’s why.

PCSX2 with a GunCon2: assign the gun to USB port 1, pick the default GunCon2 device, left mouse = trigger, right mouse = off-screen reload, middle mouse = calibrate. To calibrate, shoot the centre, press middle mouse, then A/B. At least one title needs a custom crosshair PNG because the default crosshair is offset from the actual aim point. Android’s AetherSX2 cannot do touch light gun.

The parts nobody agrees on

  • Which gun is faster. There are confident claims that a DIY camera/IR build beats a border-tracking gun on latency, and confident claims in the other direction — and no measured head-to-head anywhere. If someone says one is “faster”, ask for the measurement; the numbers aren’t in the public discussion.
  • What a Sinden costs. You’ll see “around $120” quoted. The official base price is $147.00 SGD. There is no official $120 tier. The gap is most likely currency confusion between SGD and USD, possibly a past sale — that’s an inference, not a stated fact.
  • How long a Sinden takes to arrive. The store says it ships within two weeks. Buyers report waits of six to eight months. Both can be true only if the two-week figure is handling time after purchase and the long waits are backlog or component supply. I don’t know which, and I’m not guessing.
  • AMD GPUs and TeknoParrot light-gun titles. Whether AMD cards run these titles at all is disputed, with both “works fine” and “doesn’t work” reports. Unresolved.
  • “A GunCon needs no drivers on RetroPie.” This gets asserted and then contradicted in the same discussion. It isn’t reliably true.
  • A DIY builder’s own numbers. One build is described as “around $120 including shipping” while the same parts list adds up to $80–150 before shipping. The two figures don’t reconcile.
