0.1.0-rc2

New

• Peace Walker features (PO, experimental, off by default): Game > Peace
  Walker. Import from a PW PSP disc image or Master Collection folder, turn
  the feature on, then Restart to apply. The source is not needed afterwards.
  • Fulton recovery: Triangle beside an unconscious or held-up prone
    soldier recovers him on the spot, without the truck. Snake is free once
    the balloon is attached, so recoveries chain.
  • Crouchwalking: move while crouched; hold Triangle to stalk. With the
    Mk22 out, the upper body uses PW's Mk.22 clips.
• Picture: Video > Picture.
  • Field of view: 75 to 150%.
  • Detail distance: 100 to 400%. Full-detail soldiers and their shadows
    reach farther.
• Frame interpolation
  • Prediction: Video > Timing. Cuts the delay interpolation adds.
  • HUD, menus and fades are interpolated too.
  • Show frames early and Read the controller late: Game > Response.
    Both lower input delay.
• Controls
  • First-person aim follows the stick's direction instead of snapping to
    eight directions, and weapon aim turns smoothly.
  • Analog stalking: Game > Controls. A slight tilt stalks; the threshold
    is adjustable.
• Sound mix: Audio > Mix sets music, effects and voices. PO adds
  cutscenes.
• Startup skips: Game > Startup skips the logos and the opening movie.
• PO units in PO+: New Game imports them from Portable Ops Native's save,
  with a list when there are several saves. A portable folder is not read.
• Interface
  • F11 switches between fullscreen and a window.
  • F12 saves a PNG screenshot to the data folder's screenshots/;
    System > Open the screenshots folder.
  • FPS only: a small counter, under Video > Timing > Performance.
  • Open the menu when switching away: Game > Menu.
• Data
  • Portable mode: a portable folder beside the executable holds the
    data, settings and saves.
  • Each slot's previous save is kept and loaded if the newer one is broken.
  • Each run writes a log to the data folder; the previous one is kept.

Changed

• Every stage on the disc is compiled to native code; rc1 left some to the
  interpreter.
• New players start fullscreen with Fill aspect, 4x MSAA, 16x anisotropic
  filtering, 200% detail distance, and interpolation at display rate with
  full Prediction. Existing settings are kept.
• New Game tab: Game speed, Fast loading and the menu pause switches moved
  there.
• Audio > Volume is now Audio > Master.

Fixed

• Disable camera follow (was Camera follows behind) had no effect.
• PO+ online: camera and control options had no effect in the lobby and maps.
• L + D-pad left or right looped an animation with Swap sticks in first
  person on.
• Thermal goggles showed black; night vision flickered.
• Interpolation
  • Smoke-filled rooms ran at the game's frame rate.
  • Scenery at the screen edge appeared a frame late.
  • Characters showed lit on the black screen after a loading screen.
• Saves
  • Import, export and backup missed the three save slots.
  • A crash right after saving could break the save.
  • On Windows, a file held by another program failed the save.
  • An unreadable save stopped the game.
• Menu
  • Clicking a setting's name changed it instead of selecting it.
  • Folder buttons did nothing on Windows.
  • Some text described another game.
  • Greyed rows gave no reason; Restore video defaults kept the text font.
• mpo-server: lowercase login names were refused, and adduser accepted
  passwords under 6 characters, which the game rejects.

Removed

• The Network tab (ad hoc play), until ad hoc is tested.

Not in this release

• PO online, ad hoc play in both games, PO+ EU and JP packages.

Tested

• Gameplay smoke on all four packages: Linux builds through steam-run, Windows builds under Wine 11.0.
• PO+ (Windows, under Wine): first-run ISO import, restart without setup, save reload.

Not yet verified

• Native Windows and clean-machine setup.
• Full campaign and mode coverage.
• Multiplayer. mpo-server ships beside PO+ but is experimental: incomplete protocol, and it stores account passwords in plain text. Don't expose it publicly.
• Six unimplemented imports were found; see the import audit.
