Odrannnn/MetroidPrimePort v0.20.0

on GitHub

Faster rendering, a very experimental macOS build, experimental PAL disc support, Remastered-style movement under
twin stick and mouse aim, and fixes for music after loading a save state (#52),
options lost on restart (#45), a stuck control lock after Hall of the Elders
(#44), Steam Deck trigger mappings (#53) and TLS errors connecting to
Archipelago on Windows (#51).

You need your own disc image. Metroid Prime (USA) v1.00, GM8E01 disc 0
revision 0, or (experimental) the PAL release GM8P01. Nothing here contains
any part of the game — no disc, no assets.

What changed

Performance

• Cheaper graphics command processing: far fewer pipeline rebuilds and less
  work per draw.
• Shaders compile on several threads at startup, so the startup compile
  finishes several times faster.
• The Remastered room import is faster on Android.

New

• macOS (very experimental, needs testing): a first build for Apple
  Silicon Macs (arm64, macOS 13 or later). It builds and passes its tests on
  CI, but it has never been run on a real Mac, so rendering (Metal),
  input, audio and saves are all unverified. Expect problems, and please
  report what works and what doesn't. The app is ad-hoc signed, not notarized:
  after unzipping, run
  xattr -dr com.apple.quarantine "Metroid Prime Port.app" (or right-click >
  Open) before the first launch. Settings and saves go to
  ~/Library/Application Support/Metroid Prime/. Intel Macs aren't supported.
• PAL discs (experimental): Metroid Prime PAL (GM8P01) is accepted and
  plays in its own languages (F1 > Game > Language). A USA game can also borrow
  a PAL disc's languages: F1 > Game > Language > "Add languages from a PAL
  disc...".
• Remastered movement (F1 > Controls, on by default under twin stick and
  mouse aim): movement follows the stick directly with Remastered's air drag, so
  jumps keep a smooth arc (#46). Scan dashes still work as in the original.
• Crosshair opacity and colour (F1 > Video > Display) for the centre
  crosshair of free aim, mouse aim and twin stick.
• Faster stick aim: the stick aim speed goes up to 8100 (#34). The setting
  now shows only with twin stick on.
• Sharp scan window (optional, F1 > Video > Display): the scan visor's
  magnified window renders the world again instead of zooming the screen, so
  HD textures stay sharp (#25).
• A "Press F1 for settings" hint at launch (can be turned off in F1 > Video >
  Quality).
• Every setting is written to the log, which helps with bug reports.

Fixes

• The title screen and file select no longer crawl on Direct3D 11
  (older GPUs, #54): startup shader builds wait until a game is loaded there.
• The scan's "recording to logbook" sound plays in full (#55); every
  sound with timed pauses now keeps the original's timing.
• Music keeps playing after loading a save state (#52).
• Invert Y, rumble, volumes and the game's other options are kept across
  launches and save files (#45).
• All abilities work after Hall of the Elders' wave throw with skippable
  cutscenes (#44); only the Spring Ball did.
• A trigger mapped next to a face button (Steam Deck, #53) no longer pages
  the pause menu instead of selecting.
• A shoulder button bound to a visor works under twin stick instead of
  switching beams (#47).
• Archipelago over TLS on Windows (#51): certificates are checked through
  Windows when its root store doesn't have the root yet.
• Mouse aim switches twin stick on too, and the number keys pick beams under
  mouse aim (#30).
• Toggle Lock-On latches only when something is locked on, instead of
  leaving Samus strafing.
• No thin vertical lines in the visor at non-integer render scales (#23).
• Run speed no longer depends on the simulation rate, and diagonal jumps no
  longer outrun the original's top speed.
• Archipelago: the gate of Save Station Mines A opens again (#39), and frozen
  Jelzaps' ice no longer spikes.
• The Linux build links its libraries statically; it needs only OpenSSL 3 and
  the C/C++ runtime (#27).

Remastered import (very experimental, unsupported)

The Remastered import and everything built on it are very
experimental and currently unsupported. Remove mods/remastered-models
to get the retail game back. Nothing changes unless you run the import
yourself, and nothing of Remastered ships with the port. Re-import to get
the new effects.

• The gun behaves closer to Remastered: projectile and charged-shot effects,
  no plasma muzzle flash or charge light, the holo wipe, lock-on extension,
  the Ice frost shell and Phazon charge. The Wave Beam's secondary
  electricity uses Remastered's effect.
• The Morph Ball's boost trail and colours match Remastered's.
• The Phazon Beam uses Remastered's materials and fades in as Remastered's
  does.
• Remastered particle variables, so effects that change colour or size with
  the game's state follow it.
• The import also works from a PAL disc.
