rem-essentials is a Freelancer plugin for the REM mod that collects the client/server fixes REM actually needs. The goal is to keep a single, small, configurable feature surface that works on native Windows and under Wine/Proton.

Feature surface

Every feature is individually configurable through rem-essentials.ini. Features cover the mouse/cursor stack, server-side fixes, client stability patches, navigation, graphics, saves, screenshots, logging, and more.

The Proton-sensitive mouse stack is split into separate switches:

hide the in-game cursor when the real cursor is outside the game window
prevent Windows cursor flicker at screen borders in borderless windowed mode
prevent mouse warps to the center of the game window in windowed modes
no server kick when buying the same ship again
avoid the quit-message loop hang after the game receives Quit
patch the rare alchemy.dll crash around file offset 0x77cb

Documentation

See docs/architecture.md for feature registration rules and docs/build.md for the current MSVC/x86 build path. See docs/deployment.md for release validation and packaging. See docs/configuration.md for INI precedence, Launcher overrides, manual installation, and save-directory behavior under Proton.

Design rules

Keep every fix independently configurable.
Keep client-only and server-only fixes separate.
Treat mouse/cursor fixes as Proton-sensitive and test them under Wine/Proton before enabling them by default.
Prefer small, named fixes over broad plugin behavior.
