On an 8K panel Match display asks 18x (27x with supersample 1.5), past
the full-VRAM surface: the high-resolution window engages, dynamic
resolution is ineligible there, and the render thread saturates (R4 0.8
on an RTX 4080 at 7680x4320: fixed 27x, render_busy 100 %, Low 51.9
guest Hz). A game.toml key caps the display height that Match display,
its dynamic-resolution floor and preset detection resolve against.
Default 0 keeps today's behaviour for every title.

Keep selector zero stock and seal all choices until the next session restart. Refuse nonzero online activation, scope non-stock save states by frozen choices, and preserve original instruction guards when combined with effective-address adapters. Use overlay ABI34 on current master without the old menu dependency stack.
Extract the audited adapters and card transport onto master without the held selector/menu stack. Keep adapters and codecs tied to mod activation, use overlay ABI 33, retain rejected-load protection on codec registration, and refuse extended-card codecs in netplay before frame zero. Preserve default atomic save publication and guest-visible write failures.
Renderers that test a 16-bit screen X with an unsigned compare against a width kept in a register (often a loaded clip bound) reject every negative X, so widening the bound only reveals the right band. A screen_x site on sltu now routes through psx_ws_cull_sltu_band: -4m <= (int16)SX < W while widened, identity at 4:3. Four margins keep large near polygons whose corners all lie past one margin; an unbounded left side overflowed a renderer's fixed primitive lists. Covered by ws_cull_screen_x_hi_codegen_test; documented in WIDESCREEN.md.
- [quality.*] accepts only the supported keys (quality_key_supported):
twelve player-editable ones (masked, copied, classified, applied) and
nine preset-only ones (no settings.toml form; applied on select). Any
other key, e.g. vsync or renderer, is a load error.
- Picking a preset now also applies bloom, texture LOD, anisotropy, FMV
chroma smoothing and dithering (quality_apply_video_globals).
- The frontends flag Custom on any tracked row; the host counts only rows
of keys the title governs (psxq::launcher_custom_edit), so Antialiasing
no longer turns Ultra into Custom when no preset sets it.
Tests cover the rejection, every player key's masking/copy, and the
classification cases.
