This is intentionally a native-behavior catalog, not a mandate to reproduce every Win32-era switch. The
current port already preserves the shipped result of several settings through profile-specific constants:
the `800x600` canvas, requested Mincho/Gothic faces, save version 3.10, and movie/audio behavior. It
deliberately redirects the native AppData path to Godot `user://SAVE`, and it should not reproduce legacy
DirectDraw selection or native registration/key validation.
This is intentionally a native-behavior catalog, not a mandate to reproduce every Win32-era switch.
`Sys4AssetCatalog` now parses the ordered trailer once, retaining unknown pairs for diagnostics, and projects
`SCREENX`/`SCREENY` into one validated engine-owned logical canvas. Godot uses that value for its content-scale
base, default windowed client, backbuffer/compositor bounds, primary surface, movie/layout fallbacks, and input
coordinates. AGE's independent `640x480` defaults apply for missing or invalid dimensions. The port still
preserves requested Mincho/Gothic faces, save version 3.10, and movie/audio behavior through their existing
paths; those keys have not yet been migrated to the parsed registry.
The actionable generic-profile gap is that `Sys4AssetCatalog` still parses only the directory and the frontend
hard-codes the important results. A future configuration/profile slice should expose the typed trailer values
once and let the runtime apply only cross-platform semantic settings. In particular, click-cancel, Auto/Skip
coexistence, cursor policy, redraw policy, and wheel action ids must be decided from this evidence instead of
AGE's compiled defaults. No runtime behavior changes were made as part of this investigation.
The remaining generic-profile gap is semantic application of further portable settings. In particular,
click-cancel, Auto/Skip coexistence, cursor policy, redraw policy, and wheel action ids must be decided from
this evidence instead of AGE's compiled defaults. The port deliberately redirects the native AppData path to
Godot `user://SAVE`, and it should not reproduce legacy DirectDraw selection or native registration/key
validation.
