Load modern texpage/texupload PNG replacements independently of DuckStation source. Integrate pack folders and options with mods, preserve native VRAM, and validate GL rendering, format matching, dump safety, and upload invalidation.
A [[plugin]] may declare netplay = "local_view": it only changes what one
player sees. A netplay session now keeps the player's own features whose every
contribution is such a plugin (no writes, overlays or derived discs) instead of
clearing them, without saving state.toml. They activate as usual, but their
hooks run only inside psx_mod_render_local_view (psx_mod_local_view_scope) and
their vblank/savestate callbacks not at all. With such a plan the widescreen
cull margin is the stock 0 in the shared game and this peer's own margin only
inside the sandboxed own-view draw; squash is not used. The canonical frame,
snapshots and digests stay identical on every peer whatever each player chose,
so nothing is negotiated, and each keeps their own aspect.
Tests: netplay_view_mods_test (flag, plan filter, parked hooks, no vblank,
state.toml untouched), ws_local_view_margin_test (margin scope), render-pass
sandbox asserts the scope around a local view.

Trusted game code can register entry hooks and consuming filters that run
only in a netplay session (psx_game_register_netplay_function_entry /
_filter). They live outside the mod package plan, which every online
match clears, so a title's netplay support survives it. Offline they are
inert unless PSX_GAME_FILTER_OFFLINE_PROBE=1. Reimplemented on master's
entry-filter path from the R4 Link Battle branch.

Preserve current segmented dispatch, active-plan mod hooks and software scale limits. Extend function filters through the active plan, retain the last-store pointer with overlay ABI 25, and keep default config fingerprints stable. Refresh BIOS emitter stamps after byte-identical regeneration and reconcile regression fixtures.
Only CPU stores are cache-isolated. Mods, the FMV skip, debug pokes, the
bg2d ring fill and the exception sentinel write guest memory from the host;
they now go through psx_host_write_*, which bypasses isc_store the way DMA
does, so a host store inside a FlushCache window reaches memory instead of
rewriting an I-cache tag. The render-pass checkpoint restores the new depth
counter like the DMA depth. isc_store_test covers it (a lane-0 host store in
tag-test mode would otherwise mark a cold line valid).
Docs: the SCPH-1001 residual starts at kernel init 0x598, and without #429
the fix removes 113 of the 126 OpenBIOS flush cycles.

Adapt the 8 MB RAM work from the rbengine branch into a master-targeted change. The builtin package is disabled by default, activation requests expanded RAM before memory init, and runtime/state/digest/dispatch paths respect the live RAM map.
Port the launcher-facing hidden feature plumbing from rbengine-bak PR #207 without resurrecting the removed 8 MB RAM manifest on master.
Source commit: 45253daf9a
A plugin that draws its own overlay primitives needs to know where the
right-hand edge of the screen is, and it cannot work that out for itself.
GPUSTAT carries the horizontal-resolution bits, so a plugin can recover
the coarse mode width, but the visible width also depends on the GP1(06h)
X1/X2 range -- and that register is write-only and mirrored nowhere a
plugin can read.
Ape Escape is the worked example. It scans out 384 (368-mode, dot clock 7,
horizontal range 539..3227) while its mode width is 368, and the usual
assumption of 320 is wrong by 64. A HUD row right-aligned to 316 lands 68
pixels short of the edge, which is exactly what the Quick Gadget Select
mod does today.
psx_mod_display_width()/psx_mod_display_height() return what the presenter
uses, straight from gpu_get_display_info(). Zero means the geometry is not
established yet, and the header tells callers to skip drawing rather than
substitute a guess -- an overlay in the wrong place is worse than an
overlay that waits a frame.
mod_runtime_test covers the passthrough with a stubbed GPU, including the
384-vs-368 case that motivates it and the zero case.

Players asked for CD speeds beyond the curated 2x/4x list and for the two
loading accelerators to stop being one control (GH TombaRecomp#5: a
speedrunner wants shorter loads but NOT the host speed-up, which runs past
the loading screen and breaks a skip).
Three changes, all general:
- psx_mod_set_disc_speed accepted only divisor 2 or 4. That was policy,
not safety: cdrom.c divides the sector delay and floors the result at
CDROM_MIN_DELAY, and apply_speed leaves XA streaming at authentic
timing, so no positive divisor can produce a zero-delay storm or
pitch-shift FMV audio. Accept 1..PSX_MOD_DISC_SPEED_MAX and let the
mod's description carry the risk warning.
- psx_mod_set_load_acceleration accepted 2..16. Host pacing cannot desync
the guest at all (every frame, CD deadline, interrupt and callback still
happens), so the ceiling was arbitrary. Accept 1..PSX_MOD_LOAD_ACCEL_MAX,
with 1 meaning authentic and 0 still meaning uncapped.
- New option key disabled_by: an option names a BOOLEAN sibling that
overrides it, so "tick Instant and the speed box stops mattering" needs
no second widget type. The parser rejects a dangling, self-referential
or non-boolean reference rather than leaving a control silently always
enabled, and the provider resolves the link against the live selection
so the launcher and the plugins can never disagree about whether a
control counts.
