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.
* feat(widescreen): continue framebuffer-feedback sprites into native-wide bands
Titles tag a 15-bit sprite that copies a framebuffer 1:1 (gpu_ws_tag_feedback_rect / psx_mod_tag_feedback_rect). Where it touches the draw area's edge, gpu.c emits band spans and the new optional backend op wide_feedback_rect (GL incl. render thread, software) samples the source buffer's wide surface. Band texels count as bit 15 set, as the centre does once the trail blends.
The software rasterizer now writes the texel's bit 15 into the framebuffer, and wide_full can dump the surface alpha ("alpha":1).
* fix(widescreen): quantise band feedback like packed VRAM
The centre samples 5-bit packed VRAM each frame; the band copy read the 8-bit wide surface and modulated with /128, so the bands drifted ~3 grey levels brighter and left a step at the 4:3 edge. Truncate like PACK_FS and modulate like TEX_FS.
* Reject fully clipped sprites before extending feedback margins
* Complete isolated resident and PGXP fixture collaborators
* Preserve existing line endings in the review fixes

regen_bios_profile now records generated/<out_stem>.emitter.sha via tools/bios_emitter_fingerprint.cmake, like tools/regen_bios.sh, so the next configure does not report the fresh BIOS as STALE.
Bit 29 is Beetle's InCommand. The hardware decodes progressively and stalls
while its 32-word OutFIFO is full, so a decode command stays in progress until
all but the last FIFO load of its output has been read. mdec.c decodes a whole
command at once and cleared the bit at execute time.
libpress DecDCTin spins on bit 29 before issuing the next frame. Reporting
ready early let Breath of Fire IV's FMV player issue the next DecDCTin and
DecDCTout while a column DMA was mid-transfer; DecDCTout's CHCR=0 restart
dropped the 205 words already moved, so every later column read started 820
bytes late (vertical stripes at macroblock edges, a one-macroblock vertical
wrap and shifted colour channels in the intro FMV).
Derive the bit from the unread output instead. No new state, so snapshots
are unchanged. Adds mdec_busy_drain_test (fails on the old behaviour).
