Resident Evil Outbreak Recompiled 1.5.1

Resident Evil Outbreak Recompiled 1.5.1

An update of Resident Evil Outbreak Recompiled, the unofficial PC port of Resident Evil Outbreak (File #1, USA) for
Windows, built by RaccoonRecomp with AI-assisted programming (Claude, Anthropic). It makes the high graphics settings
faster, adds the controller's Share and View buttons and the mouse buttons in game, and brings two camera mods: the new
REO First Person and Modern Camera 2.1.0.

Important

The game is prepared on your PC, once. Nothing of the game is in the download. After you choose your own disc
image or extracted files, the program prepares the game's code from them on your PC with the free compiler that
comes with it. This takes about 3 to 6 minutes on a modern PC. Then Start Game starts the game.

The setup is not code-signed yet, so Windows SmartScreen may warn about an unrecognized app.

What you need

• Windows 10 or 11 (64-bit) and a graphics card with Direct3D 11. Vulkan is optional and comes with your graphics
  driver.
• About 780 MB of free disk space (the program, its three background videos and the prepared game).
• Your own legal copy of the game: Resident Evil Outbreak (USA) for the PlayStation 2, SLUS-20765, disc version
  2.00, as a disc image (.iso) or as files extracted from your disc. Other releases are recognized but not supported
  yet. Outbreak File #2 is not supported.

Install or update

Run the setup. It installs for your Windows user only by default (no administrator rights needed); Install for all
users is available too. Your settings, saves and mods live in your Windows profile, so they stay when you install
1.5.1 over 1.5.0. A first install asks for your game data and prepares the game as described in the
1.5.0 notes.

What is new in 1.5.1

• The high graphics settings are drawn faster, with the same pictures. At 4x resolution with MSAA 4x or 8x, and
  with Downsampling, the Direct3D 11 renderer draws the scene and the item screen with much less GPU time: MSAA 4x and
  8x keep a sample position that all its samples share once, runs of sprites (the item screen's layers, room effects)
  are drawn in a compute pass, and the scene's triangles use smaller shaders of their own. The item screen, which fell
  to about 13 pictures per second in the stairs room between 1F and 2F at 4x with MSAA 8x, now holds 30 pictures per
  second there (measured on the test PC, an RTX 4060 Ti). Every picture is the same as in 1.5.0 (checked frame by
  frame at many settings), and the default settings are untouched.
• Steadier while other programs run. The game's threads run on the processor's performance cores, are never
  power-throttled and run above the normal priority, at every timing setting, so other busy programs (recording
  software, for example) disturb the game less.
• Controller: Share and View (Xbox Series X|S controller). Share opens the program's menu over the running game
  and is Back in the menus, as Escape is; the game never sees it. View opens and closes the camera window while a
  camera mod is switched on in Mods (also when the camera's own On / Off is Off); View + Menu stays the program's menu,
  and with no camera mod on View is the game's Select as before.
• Keyboard and mouse in game. The right mouse button readies the weapon (R1) and the left mouse button is Cross: it
  fires while the weapon is ready. Enter confirms the game's own menus before play (main menu, scenario, character
  and difficulty choices: the new Controls row Cross in Game Menus) and is Start in a scenario. The mouse buttons are
  on port 1 of both input layouts; all of them can be rebound on the Controls tab, and an existing input.ini gets the
  mouse buttons where they are still free.
• Camera mods.
  • The camera window carries the camera mod's own name (the Modern Camera's window is unchanged). With a controller,
    Left and Right move between its Reset to defaults and Close buttons.
  • A camera mod can lock its window ("locked": true in its window_layout.json): the window and the mod's
    Configure page then show every setting with its value, but nothing can be changed and there is no Reset to
    defaults.
  • The program has the room-draw event the camera mods need to draw J's Bar's restroom mirrors with the game's own
    functions.
  • REO First Person has its own code sites, compiled in at the first preparation like the Modern Camera's and the
    Cheats'; a site both camera mods name is compiled in once, and each mod's entry on the Mods tab shows its own name
    for what it switches.
• The official mods' code sites in the program are those of Modern Camera 2.1.0, REO First Person 1.0.0 and the
  Cheats 1.2.0.

The mods

The mods are separate downloads (see the project page). New with this release:

• REO First Person 1.0.0 (REO-FirstPerson): an original
  first-person camera. The camera sits in your character's eyes and follows the head, lines up with the gun's sights
  while you aim, and the right stick looks around from her eyes. J's Bar's restroom mirrors show the room reflected.
  Its camera window is locked: you see its settings, but they cannot be changed.
• Modern Camera 2.1.0 (REO-ModernCam): the camera stays on your
  character (knockbacks, hits, recoil and the game's auto-aim no longer swing it), Lock On Enemy (the camera turns
  onto the enemy the game's aim locks onto), the walls and pictures of the rooms stay drawn, J's Bar's restroom mirrors
  show the room reflected, and the controls are the game's own while the camera is handed back to a cutscene.

Use one camera mod at a time: the Mods tab reports a conflict when both are on.

Known issues

• Downsampling with the item screen: with Resolution 4x and Downsampling 2x, the item screen still stays below
  30 pictures per second (measured on the test PC). It is the one setting where that was found.
• Share needs Bluetooth: the Share button works only when the controller is connected over Bluetooth. Over USB or
  the Xbox Wireless Adapter Windows does not report it; hold Back + Start to open the menu there.
• Switching a camera mod off during play: after a camera mod is switched off mid-game, your partners may stand
  somewhere else than where they were.
• The Greatest Hits Cheats download carries no code sites. Its cheats marked game data or save data work; its
  cheats marked game code do not act in the game prepared on your PC.
• On a PC with Smart App Control or an App Control policy, Windows may block the game file built on your PC. The
  program explains what happened.
• Only the USA release, disc version 2.00, is supported.

The setup is not code-signed yet, so Windows SmartScreen may warn about an unrecognized app.

What you need

• Windows 10 or 11 (64-bit) and a graphics card with Direct3D 11. Vulkan is optional and comes with your graphics
  driver.
• About 650 MB of free disk space (the program, its three background videos and the prepared game).
• Your own legal copy of the game: Resident Evil Outbreak (USA) for the PlayStation 2, SLUS-20765, disc version
  2.00, as a disc image (.iso) or as files extracted from your disc. Other releases are recognized but not supported
  yet. Outbreak File #2 is not supported.

Install

1. Run the setup. By default it installs for your Windows user only (no administrator rights needed). Install for
   all users is available too.

2. Start Resident Evil Outbreak Recompiled and choose your game data. You have three options:

   • select your ISO;
   • select a folder of extracted files;
   • put either one into the installation's empty ROM folder. The program then offers it as Use <name>
     from the ROM folder.

   Your game data is only read, never modified or copied. Only its location is saved.

3. The program prepares the game from your game data (Preparing your game...). When it says Game code prepared.,
   choose Continue, then Start Game.

What is in 1.5.0

• The game preparation. After you choose your game data, the program prepares the game's code from your own disc
  on your PC, once: converted and compiled there with the included free compiler (LLVM 23.1.2, Apache License 2.0
  with LLVM Exceptions; its licence files are installed with it). Nothing is downloaded for this, and nothing from your
  disc leaves your PC.
  • It takes about 3 to 6 minutes on a modern PC: about 3.5 minutes measured with 2 compiler processes, up to about 6
    when the PC has little free memory. Later starts load the prepared game right away.
  • The code sites of the Cheats' game-code cheats and the Modern Camera are compiled in during that one
    preparation, so these mods work as soon as you switch them on.
  • The prepared game was checked against the developer's own build: identical, and not slower. With the Cheats'
    game-code cheats and the Modern Camera on, it matched as well.
  • The prepared game is kept in your profile (%LOCALAPPDATA%\Resident Evil Outbreak Recompiled\GameCode).
• The program and its PC runtime. The game's code is recompiled to native x64 code and runs at its original
  30 fps. An optional 60 fps mode is available (experimental).
• Graphics:
  • Direct3D 11, Vulkan and software renderers.
  • Internal resolution up to 4x or Auto, with downsampling.
  • MSAA up to 8x and FXAA.
  • Texture and anisotropic filtering.
  • Nearest, Bilinear and Sharp Bilinear scaling.
  • Widescreen with HUD placement (experimental).
  • CRT effect, color filters and Reduce Flashing.
• Controls:
  • Controllers and keyboard and mouse, fully remappable.
  • PlayStation, Xbox or keyboard button symbols.
• Three built-in background videos for the menus (REOUTB, the default, REOUTB 1 and REOUTB 2), chosen in Settings > General > Background Video; they play behind the main menu, the game data screen and the Preparing screens.
  • Compensate Game Deadzone, Mouse Acceleration and Hold To Toggle.
• Saves: a virtual memory card in the same raw .ps2 layout as PCSX2, with backups, Save Profiles and Portable
  Saves.
• Mods: the mod framework and its Mods tab. The Modern Camera and the two cheat mods are separate downloads; see
  the project page.
• The fresh start: the installation brings an empty ROM folder for your own game data and installs no settings
  file. The program starts on its game data screen.
• Installer: installs per-user by default. Repair, Modify and Uninstall are supported, and uninstalling keeps your
  saves and the prepared game unless you choose to remove them.

Known limitations

• The Greatest Hits Cheats download carries no code sites. Its cheats marked game data or save data work; its
  cheats marked game code do not act in the game prepared on your PC. (The Cheats and Modern Camera downloads carry
  their code sites.)
• On a PC with Smart App Control or an App Control policy, Windows may block the game file built on your PC. The
  program explains what happened.
• Only the USA release, disc version 2.00, is supported.
