A host built against a recomp-ui without the Internal resolution row
(RECOMP_LAUNCHER_HAS_INTERNAL_RESOLUTION undefined) still seeded
internal_resolution on first boot and applied it after the launcher.
From a fresh start the seed was "native", so a Supersampling pick of 3x
was reset to 1x and "native" was saved; on the netplay soft-return the
sticky preset was re-applied at session_reboot. The legacy row stopped
working.
Both launcher exits now go through two pure helpers in
internal_resolution.h:
- psx_ir_launcher_seed_supersampling: with the row, the factor as before;
without it, the factor itself when no preset is configured (the
historical round trip), else the preset's scale capped at the row's 4x.
- psx_ir_adopt_launcher: with the row, the row's preset as before;
without it, a pick in the Supersampling row drops the preset, and an
untouched row keeps a preset the player cannot see (game.toml or a
hand-edited settings.toml). It also returns what settings.toml saves:
no internal_resolution key unless a preset is kept.
internal_resolution_test drives seed -> launcher -> adopt for both
launcher kinds, first boot and soft-return, against a model of the
legacy row (clamp to 1..4, cycle); keeping the old sticky preset fails
it. gl_internal_scale_guards pins both exits to the helpers.

Add a player-facing internal resolution on top of the raised GL ceiling.
A preset is a target height; the runtime renders at the integer scale
S = ceil(target / reference_lines), reference 240 by default: 720p 3x,
1080p 5x (area-resolved to 1080), 1440p 6x, 4K 9x, 5K 12x, 8K 18x. The
backend then clamps S to what it can allocate.
- runtime/include/internal_resolution.h: the preset table, stable ids,
the value encoding shared with recomp-ui (0 unset, 1 native, -1 match
display, N target lines) and the pure resolver.
- config: [video] internal_resolution (a preset id or a number of lines)
and resolution_reference_lines in game.toml; internal_resolution in
settings.toml, written as a stable id beside supersampling = min(S, 4)
for older runtimes. Precedence: game default < player's legacy factor <
player's preset. settings.toml window_width now accepts up to 7680.
- main.cpp: resolve the preset before gpu_init; Match display re-resolves
from the game window's monitor (SDL3 mode height x pixel density) before
the GL context allocates. The launcher gets the vocabulary (with a
synthesized "Nx (L lines)" entry for a legacy factor no preset matches)
behind RECOMP_LAUNCHER_HAS_INTERNAL_RESOLUTION, on first boot and on the
netplay soft-return.
- The OpenGL game window gets SDL_WINDOW_HIGH_PIXEL_DENSITY (SDL2:
ALLOW_HIGHDPI) only when the player chose more than native, so the
drawable is in pixels on Retina; native keeps the window as it was.
- debug server: video_info (preset, requested and effective scale, GL
limit and clamp, hr surface, window points vs pixels), screenshot_hires
reads the GL hr FBO at full size, screenshot_wide_hires captures the
native-wide band at internal resolution.
- docs: config_schema (keys, precedence), NETPLAY (a per-peer presentation
setting), TCP_COMMANDS (index regenerated), ENHANCEMENTS IR1.
Default-off: with no internal_resolution anywhere the scale, the window
flags and the present path are unchanged.
Tests: internal_resolution_test (presets x reference 240/480 x backend
maxima, legacy mapping round trip), video_enhancement_settings_test (game
and settings keys, stable-id round trip, legacy key still written),
gl_internal_scale_guards (HiDPI only when opted in, launcher fields behind
the capability macro).
