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.
Apply committed sector mods during plugin activation, resolve paths through
patched directory records, and bound file size by CD capacity.

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.

The lobby rematch re-enters the emulator through goto session_reboot,
below the first-boot session block. After its commit (offline) or
netplay clear it reset mod-owned presentation state, but it never ran
mod_runtime_activate_plugins() or the controller, load-acceleration and
disc-speed resets. So an offline rematch with mods enabled applied the
plan's main-EXE and disc patches and ran its VBlank callbacks, but no
activation callback ran, and the function-entry hook table, which the
commit empties and only activation rebuilds, stayed empty. It also
mounted the stock disc even when the plan had built a derived disc
image.
start_mod_session() now holds the first-boot sequence, unchanged:
clear the controller-mode overrides and presentation policies, load
acceleration and disc speed; run reset_mod_owned_presentation();
activate; then apply the netplay local viewport, the controller-mode
overrides and load acceleration. The first boot and the rematch both
call it after their commit or netplay clear, and both then take the
mounted disc from session_disc_path(), which returns the plan's derived
image when there is one and otherwise the stock disc. Activation still
precedes renderer and window creation on the rematch, because those
happen after session_reboot on every session. The rematch re-applies
its 4:3 Settings clamp before the session start, so a plugin's
activation or the netplay local viewport can still set the aspect.
A netplay rematch clears the plan, so activating it runs nothing and
the match stays vanilla. The first boot's behaviour is unchanged.
Tests: test_mod_owned_display_controls.py now requires activation and
the mod-owned reset to happen only inside start_mod_session, in the
order reset, activate, apply. It requires both paths to call it after
their commit and before the disc mount, and the rematch 4:3 clamp to
come before it. mod_runtime_test adds the lobby rematch sequence:
activating after a netplay clear runs no callback, VBlank plugin or
hook; the offline rematch's commit and activation re-run the
activation callback and VBlank plugin and arm exactly the plan's hook.
test_mod_load_acceleration.py follows the reset block into the lambda body.
Two comments that said a soft return never re-applies the controller-mode
override are corrected: test_launcher_pad_mode_wiring.py and
test_launcher_pad_mode_resolve.cpp. MOD_PACKAGES.md now describes the
rematch as a full session start.

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.
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.
