The aircraft's ground shadow is drawn with the Xenos CONSTANT_ALPHA blend factors, which dfd8b92a routed to D3D12's ALPHA_FACTOR family, an OPTIONAL feature that must be checked via OPTIONS13::AlphaBlendFactorSupported first. We never checked, so on a device reporting false the shadow's pipeline is rejected and, being indistinguishable from one still compiling, its draw is dropped from every frame in silence. Now the capability is queried, and where it is absent the pixel shader carries the blend constant's alpha in its alpha output so INV_SRC_ALPHA reproduces the same blend exactly.
The game now mounts straight from a .iso beside the exe (selected by
title id; the assets folder still wins, and loose files layer over the
image so mods need no extraction), and DLC mounts straight from raw
STFS containers in a dlc folder, any layout, title updates ignored.
Disc image device ported from Xenia (BSD); one log line per source.
This reverts commit edcb6314f2b1b06e70dbb214674eb7c2325f8ab1. The fold was a mitigation: the doubling was never in the assets but came from the decoder dropping straddled-header frames, letting the premix streams drift and comb. With the decode fixed at the root, the full summing fold is clean and cutscenes regain centre and rear content.
AC6's cutscene mixer submits its 5.1 premix to all six speaker slots as decorrelated near-copies of one mix; six real speakers separate them acoustically, but the port's 6→2 fold sums them, combing speech into the long-reported doubled dialogue. While the demo sequencer ticks, fold only the fronts (verified lossless). audio_cutscene_downmix (default on).
ac6_widescreen = true (default false), renders missions at the window's aspect ratio (hor+) by patching the game's per-camera aspect data, so FOV, culling and every camera follow. Menus, hangar, briefing and FMV revert to 16:9 and letterbox. The HUD is pre-squeezed at draw time to stay crisp, and marker art is squared without moving the aim points. ac6_widescreen_cinematics enables it in in-game cutscenes(default true, gated).
Add a native SDL3 audio driver for non-Windows hosts and gate WASAPI to Windows-only builds, so Linux builds no longer depend on Windows headers while keeping runtime telemetry and queue behavior intact.
