v1.0.4

Retail PS2 GunCon2 lightgun co-op via a separate -datapath config (Crisis Zone, Vampire Night, RE Dead Aim, RE Survivor 2, Time Crisis 3), plus a native settings page for the retail GunCon2 device. Namco arcade support unchanged.

v1.0.3

GunCon2 lightgun crosshair fix.

• Fixes the software crosshair freezing at screen center when relative-aim keys (RelativeUp/Down/Left/Right) are bound on a GunCon2 port, for example after running PCSX2's Automatic Mapping. When an absolute pointer (a lightgun) is live, the crosshair now follows the gun's absolute position and keeps tracking through the arcade game load, instead of being driven by the idle relative-axis path.
• Internal robustness cleanup: the crosshair texture is cleared via the slot it actually occupies, removing a latent edge case where a slot change could leave a stray cursor.

Aiming and shooting are unchanged. The normal no-binds paths (single-gun Game Mode via the evdev lightgun source, and Desktop Mode) are unaffected.

Install: the in-app updater will offer this automatically, or download the AppImage below.

v1.0.2

Fixes for new users and the two-gun setup.

What changed since v1.0.1:

• Direct launch fixed. Running a game straight from the emulator (not through ES-DE) now works. A portable.ini placed next to the AppImage is honored, so the emulator finds your BIOS and dongles instead of failing with "Boot File Not Exist". See the Data location note in the README.
• Sinden auto-discovery by name. PCSX2_EVDEV_LIGHTGUN=auto identifies a gun by "sinden" in its device name (the previous USB vendor match was a shared hobbyist ID, not Sinden specific).
• Two-gun smoother rig: more robust slot assignment. A smoother device that initializes slightly after a raw gun now reliably takes over its slot, so a gun is not left stranded on the raw device.
• Build robustness. Tag fetching is pinned in CI so the in-app updater stays enabled.

Existing users can update in place via Help > Check for Updates. New users: download the AppImage below and chmod +x it.

Steam Deck / Sinden lightgun v1.0.1

Maintenance release. Documents the in-app updater in the README; verifies the updater download-and-replace. Same functionality as v1.0.0 (single Sinden lightgun, Game Mode aim).

Steam Deck / Sinden lightgun v1.0.0

Steam Deck / Sinden lightgun fork, v1.0.0. First semver release.

Single Sinden lightgun support for NAMCO System 246/256 arcade gun games, including Game Mode (gamescope) aim, where stock PCSX2 lightgun aim does not work.

What works

• Game Mode (gamescope) lightgun aim via a direct evdev absolute-pointer source (PCSX2_EVDEV_LIGHTGUN=auto). It now finds a stock Sinden gun automatically (USB vendor 16c0, or "sinden" in the device name), so a new user does not need our smoothing setup. Works in Desktop and Game Mode.

Scope

Single-gun only. Two-player does not work: Vampire Night, the only System 246/256 two-guns-on-one-screen lightgun title, drives its guns through an undocumented gun board that no emulator reproduces. The System 246/256 emulation and per-game gun handling are upstream pcsx2x6's; this fork adds the Game Mode lightgun source.

Install

Download pcsx2x6-SteamDeck-v1.0.0-x64.AppImage, chmod +x, and run. See the README for setup.

Notes

Based on upstream pcsx2x6 and PCSX2.
