Model 3-Vulkan v0.9.8.3b is released. A Vulkan-focused fork of Supermodel, the open-source Sega Model 3 arcade emulator.

Model 3-Vulkan Changelog:
Model 3-Vulkan v0.9.8.3b is a maintenance update for the v0.9.8.3a milestone. It fixes a regression that silenced sound effects in every title and completes the native DDS path for HD texture packs.
🔧 Fixes
Sound effects restored in every game. A misplaced else in CSoundBoard::RunFrame() cleared the SCSP output buffers immediately after the sound board filled them, so only the MPEG music survived. Engine, tyre, collision and menu effects were silent on fresh boots and on loaded saves alike; they are back now. Music playback, the quad-to-stereo fold and existing save states are unaffected.
🖼️ HD Texture Packs
.dds / .dds.zst support — BC1, BC2, BC3, BC5 and BC7 images go straight into VRAM with the mip chain from the file (no blit pass). Files are uploaded in resumable chunks, so a 4096×4096 BC7 chain no longer starves the staging ring.
Pack order is .dds.zst > .dds > .webp > .png when several files carry the same hash.
F4 toggles replacements and F3 rescans the folder, so a pack can be compared against the original artwork without opening the in-game panel.
🛠️ Under the hood
SM3D_AUDIO_LEVEL=1 now reports the source peak split into front and rear channels, which makes "the machine is playing but one channel is missing" visible in the log.
The 3D scene targets are handed to the 2D compositor on every exit path (including the white-flash frame), and new targets are transitioned before the first composite, so VUID-vkCmdDraw-imageLayout-00344 no longer appears after a flash frame.
A same-layout write-after-write barrier was added for attachments cleared at the start of a scene pass, closing a cross-submit hazard visible to synchronisation validation.
Compatibility: save states written by v0.9.8.3a (and by the Supermodel-VK fork) load unchanged; SUPERMODEL_VERSION is untouched.
