Dead Rising 2: Case Zero — Native PC Recomp v1.0.1

A maintenance release: it fixes the first-session stuttering several players
reported, adds subtitle-language selection and an intro-logo skip to the
launcher, fixes firearms firing by themselves while aiming with the mouse, and
makes Exit Game actually exit.

Upgrading from v1.0.0: unpack over your existing folder, or anywhere —
saves and settings live outside the game folder and are untouched. Your
unpacked game data and shader cache are reused; the menu and prompt assets
regenerate once on the first launch.

Fixed

• First-session stuttering. Reported after v1.0.0 by players on their first
  run: long hitches, occasionally a multi-second freeze, easing off in later
  sessions. Graphics pipelines were being compiled on the frame thread the
  moment something new came into view, and the pre-warm meant to prevent that
  could not help a brand-new install — it can only rebuild what already
  existed. Pipelines are now built on a background thread, and the pre-warm
  chains onto shader translation so it works from the very first session.
  Measured on a simulated fresh install: zero frame-thread compiles, no outdoor
  frame over 100 ms, and a second session that starts fully warm.
• Firearms firing by themselves while aiming with the mouse. Holding right
  mouse to aim was also holding the controller's fire trigger, so automatic
  weapons emptied themselves; the handgun and shotgun were unaffected, which is
  why this survived to release. Right mouse now aims and nothing else.
• Exit Game → Yes now quits to the desktop instead of doing nothing.
• Permanent freeze on the loading screen on some machines (seen on an AMD
  Ryzen 5 5500 / RX 6600 system). A kernel semaphore our runtime implemented
  without its maximum let a work counter run away and starve the streaming
  loader. Fixed; the same machine now reaches the title and gameplay.
• AMD GPUs: the renderer now negotiates its depth format. The depth format
  the Xbox 360 uses isn't sampleable on AMD cards; the renderer now falls back
  to an equivalent one automatically. Required for the game to render at all on
  Radeon.
• The smoothing seed no longer gets lost. The shipped list of ~1,400
  graphics pipelines to pre-build was silently replaced by a much smaller
  per-machine list after the first session (or after any session that didn't
  get past loading), bringing back first-encounter pop-in it was meant to
  prevent. The two lists are now merged.
• Low-core-count machines get a fairer thread budget (6-core CPUs now get 3
  background workers instead of fewer).

Added

• Subtitle language, in the launcher. All six languages on the disc —
  English, French, Italian, Spanish, Japanese, Korean. Menus and subtitles
  follow your choice; it applies on the next launch.
• Skip intro logos, a launcher toggle (off by default). Skips the Capcom,
  Blue Castle and Dolby sequence and goes to the title screen.

Everything from v1.0.0 still applies

The whole game start to finish, 60 fps, native keyboard/mouse with real key
icons, the restored PC options screen, MSAA 2x, adjustable FOV, real Xbox 360
audio, and a first run that builds what it needs from your own copy of the
game.

You must own the game. No Capcom content ships in this repository or in
these downloads.

How to install

1. Download the build for your system below and unpack it anywhere.
2. Copy your own XBLA package file (~825 MB, no file extension — on the
   console it lives at
   Content/0000000000000000/58410A8D/000D0000/<long name>) into the
   unpacked folder's assets/package/, or just drag it onto the launcher.
3. Run cz_runtime.exe (Windows) or ./cz_runtime (Linux). The first run
   sets everything up by itself under a progress bar. Later launches start
   straight into the game.

Requirements

• GPU + driver with Vulkan 1.3.
• Windows 10+ x86-64, or Linux x86-64 with glibc 2.43 or newer.
• Your own copy of the Dead Rising 2: Case Zero XBLA package (~825 MB).
• ~2 GB free disk after first-run unpacking.

Known issues (minor)

• On AMD GPUs (tested on an RX 6600): the zombies on the main menu may
  flicker in and out — gameplay itself was unaffected in our testing — and a
  flickering black square has been seen in-game. Both are actively being
  investigated; NVIDIA is unaffected. Also on AMD, one launch after a GPU
  driver update may sit on a black screen for a minute or two while the driver
  recompiles its pipeline cache — it is not hung, and later launches are fast.
• A subtle shading flicker on Chuck's hair in motion; real hardware does
  not show it and it is being tracked.
• The occasional spot may shade slightly differently than the console.
• Linux glibc floor (2.43): older distributions refuse to start with a
  GLIBC_x.yz not found message. An AppImage-style build is planned.
• No macOS build yet — awaits test hardware, nothing structural.

Dead Rising 2: Case Zero — Native PC Recomp v1.0.0

Play Dead Rising 2: Case Zero — the Xbox 360 exclusive prologue to Dead Rising 2 — natively on Windows and Linux. Not an emulator: the game's code is translated ahead of time and runs directly on your PC, with a Vulkan renderer, real Xbox 360 audio, and native keyboard/mouse support.

▎ The port is essentially complete. The game is 100% playable start to finish — this build has been completed end to end on both platforms — and should look right in nearly all places. A few minor issues remain (below); none block progress.

▎ You must own the game. No Capcom content ships in these downloads — the game runs from your own copy of the XBLA package.

▎ How to install — download, unpack anywhere, copy your ~825 MB XBLA package into assets/package/ (or drag it onto the launcher), run cz_runtime. The first run unpacks your package, prepares all 1,265 shaders (~10 s), and generates the menu/prompt assets from your data. Saves live outside the game folder.

▎ Highlights — the whole game completable; 60 fps (the game's own hidden mode); native keyboard/mouse with real key icons that switch with your device; the restored PC options screen with live resolution up to 5K; MSAA 2x; real XMA audio including looping ambience; texture recycling for marathon sessions; and under the hood, 57,822 PowerPC functions statically recompiled to native code.

▎ Known issues (minor) — a subtle hair-shading flicker, the occasional spot shading slightly differently than the console, the Linux glibc 2.43 floor, no macOS yet.

▎ Then requirements, the legal note, and both SHA-256 checksums.
