To separate "a 1 s burst never reaches the steady rate" from "a per-axis
multiplier", measure inside ONE hold: successive 0.25 s windows of a single 3 s
press, holding speed, attitude and starting conditions constant by construction.
rep0 rate 16 59 325 209 130 322 238 110 310 151 183
rep1 rate 52 181 231 246 236 169 368 195 181 255 182
Not usable. At 0.25 s the windows do not contain enough guest updates to average,
so rate and speed both swing 3x window to window -- the same aliasing that once
manufactured a rate-vs-speed curve, reappearing at finer resolution. The first
window is lowest in BOTH repeats, which is what a ramp would look like, but the
sequence never plateaus, so the signal cannot be separated from the sampling. No
claim either way.
Widening the window does not rescue it: 0.5 s averages well enough, but a hold
long enough to contain several 0.5 s windows bleeds speed -- and speed is the
variable under test. The two effects are entangled at this observation rate.
So the residual needs a different INSTRUMENT, not another script. Live-RAM polling
samples an unsynchronised snapshot; the question wants the craft's angular
velocity as the guest computes it, once per frame. That is a Canary-side hook --
the same shape as the existing F10 ship-capture patch -- and the rebuild toolchain
already makes it cheap. Recorded as the recommendation rather than attempted as a
seventh variation of the same measurement.
Runtime-capture harness (sylph-re container)
Screenshot-driven scripts for reading the running retail game's menus under Xenia
Canary + lavapipe, headless. They assume the container helpers screenshot,
vgamepad, pad are on $PATH and HOME=/sylph-home/re.
| Script | What it does |
|---|---|
skip_intro.sh |
Boot → main menu, unattended. Taps A only while the intro movie is actually playing (frame-to-frame RMSE), then once at the PRESS Ⓐ BUTTON title. Static logo screens are left alone, so a stray tap can never land on NEW GAME. |
wait_title.sh |
Older variant: wait for the title (green Ⓐ glyph at px 625,618) and tap A. Superseded by skip_intro.sh. |
step.sh |
One Arsenal navigation step (down/up/next/prev/none) + a compact capture: weapon list stacked over the DATA SHEET. |
sweep.sh |
Walk a whole weapon-type list, capturing only rows that show a DATA SHEET — locked rows (a "Conditions to Develop" panel) are detected by the brightness of the Range Class label box and skipped. |
type.sh |
Change weapon-type tab N times (RB) and report the header strip. |
hp.sh / cyc.sh |
Hangar hard-point carousel: cyc.sh steps it (d-pad down, not left/right) and captures the Name + DATA SHEET. |
Input timing under lavapipe: the game polls input at its own low frame rate, so a 60 ms d-pad tap is dropped roughly half the time. 200 ms is reliable; 300 ms starts to auto-repeat (two rows per press).

Guest-memory tools (no screenshots)
| Script | What it does |
|---|---|
gmem.py |
Read the live guest address space out of /dev/shm/xenia_memory_* (Xenia's backing file), addressed by guest VA. find / read / words. |
weapon_runtime.py |
Solve the Weapon/Shell struct layouts against the disc records and read the fields the disc defaults. |
unit_discover.py |
Find which runtime class carries a set of ID strings, assuming no vtable: tallies the word at pointer_site - k across distinct IDs. |
unit_runtime.py |
Same solver for the unit\UN_*.tbl definition objects (vtable 0x820af844). Unions several snapshots — unit definitions are per-stage. |
schema_order.py |
Merge a sub-record's field-declaration order across all tables (topological sort); the layout check that pins fields no table ever values. |
order_check.py |
Test offset = base + 4*index for one table's sub-record against solver output. |
grab_tutorial.sh |
Cold-boot Canary, walk to the Nth TUTORIAL entry, wait for the stage load, snapshot guest RAM. One emulator per capture — backing out of a loaded mission wedges it. |
Snapshot first — cp --sparse=always /dev/shm/xenia_memory_* snap.bin (~2 s) — and
point $GMEM_FILE at the copy; the running emulator pegs every core under lavapipe.
