Branch: feat/amiibo-steam-power (#2479), new head 44e4839 on 545fd31


The game asks for amiibo (it initializes nn::nfp at every start), but Hookshot answered every amiibo call with an empty stub, so no figure could ever be read (#621). This PR serves nn::nfp and lets the player put a dump of one of their own figures on the reader from the Insert menu.

Add to Steam and the Windows power-throttling log line, which this branch held at first, are now separate pull requests; the last commit here takes them out.

What changes

  • nn::nfp is now served by the host (host/nn_nfp.c, host/amiibo.c) instead of generated stubs: one NFC reader that is always there, as on the console with a Pro Controller or the right Joy-Con.
  • A new Amiibo row on the Insert menu's Gameplay tab lists the dumps in an amiibo folder in the game folder (HOS_AMIIBO_DIR for another folder). Choose one with Left/Right, and press Enter or A when the game asks for an amiibo. The help under the row says whether it is on the reader, whether the game is looking for it, and whether the game has read it. Once the game has read it and stops searching, the figure is taken off the reader again (or after 20 s if the game never reads it).
  • Only the player's own dumps are used; Hookshot includes and downloads nothing. The game gets what a figure keeps in the clear: its UID and amiibo ID (model info). The nickname, owner Mii and application area are encrypted on the tag with keys Hookshot does not have. The nickname shown is the file name, and an application area the game creates is kept in amiibo/appdata/<UID>.bin, never written into the dump.
  • MkwVkHost version 18: amiibo_count, amiibo_name, amiibo_choose, amiibo_state. If another open PR also bumps the version, whichever lands second takes the next number.
  • The amiibo settings applets (StartNicknameAndOwnerSettings, StartGameDataEraser, StartRestorer) stay stubs: there is no applet to show.

Credit

Ported from valentderah/totk-pc-recomp runtime/amiibo.c and runtime/nfp.c (MIT): leonelalej's amiibo support (totk-pc-recomp PR #235) with Valiantsin Dzerakh's fixes. The MIT notice is kept in host/amiibo.c and noted in host/PROVENANCE.md. totk-pc-recomp serves the nfp:user IPC commands; Hookshot serves the SDK's nn::nfp functions the game imports, and keeps the application area beside the dumps.

Verified

  • Game-free: tests/test_amiibo.py covers:

    • dump checks: size, capability container, UID check bytes;
    • the reader's states through search, found, mounted, read and taken off, and the 20 s timeout;
    • the model info layout;
    • application area create, open, get, set and flush into amiibo/appdata, with the dump never written;
    • the folder listing.

    tests/run_all.py on Linux on this branch: 396 passed, 0 failed, 12 skipped (Windows-only, PIL, dotnet).

  • In the game (RTX 3090, Linux, headless, a copy of a test save):

    • the boot log shows nfp: initialized;
    • the Gameplay tab shows the Amiibo row with a synthetic test tag (made-up UID and ID, made by the test, no real figure);
    • Enter puts it on the reader (log amiibo: Synthetic Test Tag: character 012345, figure type 02, model 0abc, series 07 and ... placed on the reader), and the row's help says so.

The Amiibo row with a test tag on the reader

  • Windows: amiibo.c, nn_nfp.c, rx_backend.c and vk_menu.cpp pass a syntax check with llvm-mingw (x86_64-w64-mingw32).

Not tested

  • The game actually reading a figure. I didn't find where the game offers amiibo (none of its English messages mention it), so the read path (search, mount, model info, application area) is checked game-free only, not in play. No real figure's dump was used.

… line for Windows power throttling

- Amiibo: nn::nfp is served by the host (host/nn_nfp.c, host/amiibo.c) instead of generated stubs: one NFC reader,
  always there, and the figure the Insert menu's new Gameplay row "Amiibo" puts on it from a dump of the player's own
  figure (540-byte NTAG215 .bin files in the game folder's amiibo folder, HOS_AMIIBO_DIR for another). The game reads
  the tag's UID and amiibo ID (model info); an application area it creates is kept in amiibo/appdata/<UID>.bin, never
  in the dump. MkwVkHost version 18: amiibo_count, amiibo_name, amiibo_choose, amiibo_state. Ported from
  valentderah/totk-pc-recomp runtime/amiibo.c and nfp.c (MIT; notice kept in host/amiibo.c and host/PROVENANCE.md).
- Add to Steam (Linux, Steam Deck): builder/linux/steam_shortcut.py writes the game folder into every Steam account's
  shortcuts.vdf (refuses while Steam runs, keeps a backup, updates its own entry in place); an Add to Steam button in
  the Linux launcher and after a build. The VDF reader and writer are lethevimlet's tools/bc250/add_steam_shortcut.py
  (lethevimlet/oot-bc250, GPL-3.0).
- Windows power throttling: Hookshot already opted out at start; it now logs whether Windows accepted it, as
  totk-pc-recomp 320a41e0dc does.
- Tests: tests/test_amiibo.py, tests/test_steam_shortcut.py.

…log move to their own PRs

The Add to Steam button and module (builder/linux/steam_shortcut.py, its hookups in
builder/linux/hookshot_builder.py, tests/test_steam_shortcut.py, the readme paragraph and
credit) and the Windows power-throttling log line (host/hos_main.c) come out of this branch,
which keeps the amiibo reader whole. Both go to separate pull requests.

…ess (#2347)

**What this is for:** a player who meets a problem presses one row in
the Insert menu, **Gameplay → Bug report**, and gets a folder with
everything the game problem form asks for: the form's answers in
`report.txt` (version, the map he is in, graphics card and driver
version, CPU, RAM and system, the options changed and the switches set),
this run's log and the run before's (the crashed one after a restart)
with his home folder and user name taken out, and a picture of the game.
Maintainers get reports with the log and the hardware from the start
instead of asking for them. **What is measured:** on Linux (Omarchy, an
Arch Linux; RTX 4090, NVIDIA 615.78.08), on `main` `ba6eef70`: the new
test passes with g++ 16 and clang 23 and fails on `main`; its cases for
the review's points (NUL bytes in a log, a picture that comes late,
which switch values are written, the reason a folder cannot be made);
`tests/run_all.py`; headless runs of this head that pressed the row (one
pressed it in Kokiri Forest, one after a `kill -9` and a restart: both
reports written, read back by a script against the logs they came from
(no file holds the home folder or the user name; each log copy is the
original line for line apart from those two), the after-crash report's
`hookshot_log.1.txt` is the killed start's whole log, and its picture
came through #926's `shot_ask`); the length GitHub takes for the link,
signed out. **Not measured:** Windows at run time (compiled and linked
only), a windowed run, the link opened in a browser (signed out or in),
AMD and Intel drivers' strings, a Steam Deck.

Refs #2346 (closed by the maintainer: tracked in this pull request).

## Problem

- The game problem form (`.github/ISSUE_TEMPLATE/1-game-problem.yml`)
requires the version, where in the game, the graphics card **and driver
version**, CPU, RAM and operating system, and `hookshot_log.txt` (and
`hookshot_log.1.txt` "if you started the game again after the problem").
The player has to find each one by hand.
- `hookshot_log.txt` answers only part of it: its first line has the
version, but the driver is only Vulkan's packed number (`vk: device 0:
NVIDIA GeForce RTX 4090, Vulkan 1.4, driver 0x99d38200, type 2`), there
is no line for the system, the CPU or the options changed, and nothing
logged where the player was (the host reads `Sequence_CurrentBanc` only
for the debug tools).
- After a crash a player starts the game again, and the crashed run's
log becomes `hookshot_log.1.txt` (`host/hos_main.c`, the rotation added
because players sent the new run's log and the crash was gone). It still
has to be found and attached.
- The logs carry the home folder and the user name in their paths (`fs:
mounted content: -> <home>/...`, `vk: pipeline cache <home>/...`), which
a player may not want to post.
- So reports arrive without the log or the hardware, and
`docs/workflow.md` scores such a report at confidence 0.4 and asks for
the log first. This gathers what CONTRIBUTING.md already asks ("Include
the version, your hardware, where you were and `hookshot_log.txt`";
"Report the version you actually ran: ... the first line of
`hookshot_log.txt`"). It changes nothing about where reports go.

## What changed

- `gpu/vk/vk_bug_report.h`, `vk_bug_report.cpp` (new, 59 + 602 lines):
the packer, without Vulkan and without the menu, so the test compiles it
alone. It writes `bug-reports/<YYYY-MM-DD_HH-MM-SS>/` in the game folder
on a thread of its own:
- `report.txt`: the form's questions under the form's own `### `
headings, so `scripts/hardware_report.py`'s `section()` reads it as an
issue: **Hookshot version** (`HOOKSHOT_VERSION`, as the log's first
line); **Where in the game** (the last `map:` line of this run's log,
and the run before's, and a request to add what you were doing);
**Graphics card and driver version** (the device and
`VkPhysicalDeviceDriverProperties`' `driverName` + `driverInfo`, e.g.
`NVIDIA GeForce RTX 4090, NVIDIA 615.78.08`); **CPU, RAM and operating
system** (the CPU's brand string and threads, RAM, `os-release`, desktop
and session type on Linux; `RtlGetVersion` and Wine on Windows);
**Changes from the defaults** (each Insert-menu row not at its default
as the menu shows it; a microphone chosen by its name is not named; then
the switches set, below); **hookshot_log.txt** (what is attached, the
run before's version and date, each log's first `FATAL`, `CRASH` or
`device lost` line); **Screenshots or video**; then a link that opens
the form with version, where, GPU, system and settings filled in (GitHub
fills issue-form fields from query parameters named by the fields' ids).
- **The switches.** CONTRIBUTING.md lists `hookshot_env.txt` among the
files never to share, so the report never copies it, and of the switches
set (the names `hookshot_env.txt` takes: `RX_`, `HOS_`, `HOOKSHOT_`,
`EDEN_`, `NVN_`, `SDL_`; and what hooks other code in:
`VK_INSTANCE_LAYERS`, `MANGOHUD`, `ENABLE_VKBASALT`, `LD_PRELOAD` ...)
it writes each name, and the value only when it cannot hold anything
private: a number of at most 12 characters, a size such as `1920x1080`,
or on/off, true/false, yes/no, and never for a name with `TOKEN`, `KEY`,
`ROOM`, `SECRET`, `PASS`, `SERVER` or `USER` in it. Every other value
reads `(value left out)`: paths, addresses, scripts. Other variables are
not listed at all.
- **The link** stays within 2000 characters and carries no switch value:
the options changed and the switches' names, or, when the names do not
fit, how many switches are set. A player who is not signed in is sent to
GitHub's sign-in page with the whole link inside it, and that page
failed for links from about 3500 characters of escaped text (table
below).
- `hookshot_log.txt` (this run's log up to the press) and
`hookshot_log.1.txt` (the run before's; when this run logs elsewhere,
e.g. from a terminal, the game folder's `hookshot_log.txt`). Read by
length (`fread`, split on newlines), so NUL bytes, which a run ended by
a power cut or a hard kill can leave, are copied as they are. Each line:
the home folder (a whole folder; on Windows either slash and any case)
becomes `~` or `%USERPROFILE%`, the user's name as a folder of any path
`<user>`. A log over 10 MB keeps its first MB and its last 9 MB (GitHub
takes files up to 25 MB).
- `picture.png`: 1280x720, the game's next frame, without the menu
(below). If none comes within 3 s, the report goes without it and says
so; a picture that comes later is deleted again.
- A folder that cannot be made is reported with the system's reason
(`GetLastError()` on Windows, `errno` elsewhere).
- `gpu/vk/vk_menu.cpp` (+89): the row before Restart and Quit
(`kBugReportRow = kRestartRow - 1`), its help (what goes in, that no
saves or game files go in and nothing is sent), its value (Press to save
/ Saving... / Saved / Not saved), Save in both prompt lines (the full
menu's and the compact bar's), the press, `changed_rows_text()` (rows
against a default-constructed `Options`), `bug_report_save()`, and the
picture's ask, `bug_report_picture()`. It follows Save my pipeline
list's pattern (#2447): its value in `row_value_cell`, its line under
the help in `draw_options` once pressed (where the folder is and how to
send it: File Explorer on Windows, a file manager on Linux; on a Steam
Deck, Desktop Mode), and room for that line's longest form in
`measure_help`. The game opens no browser or file manager: Game Mode on
a Deck has neither.
- `gpu/vk/vk_replay.cpp` (+2): `shot_ask_next()`, which calls #926's
`shot_ask(path, -1, done, ctx)` from outside its anonymous namespace
(declared in `vk_internal.h`). The report's picture is the control
bridge's kind of shot: an image and a buffer of its own (1280x720, made
at the first ask), copied from `src`, the game's frame, which the menu
is never drawn into (`menu_record_image` draws only into the
screenshots' image), read back once the GPU is past it and written on a
thread. No other line of `do_present` changes.
- `gpu/vk/vk_main.cpp` (+11), `vk_internal.h` (+6):
`device_report_text()`, and the declaration above.
- `host/hos_main.c` (+12): `map: <Sequence_CurrentBanc> (child|adult)`
when the map or the age changes, in `oot_inventory_refresh` (on Link's
update, at most every 500 ms, where the age is already read for the
Debug tab). It is where the report's place comes from, and it puts the
place into every log. The names are the game's own map names, which the
debug tools' teleport lines already print.
- `readme.md`: the row in the menu table, a paragraph on what it saves
and which values it leaves out, a pointer from "If the problem
continues".
- `tests/test_bug_report.py` (new), and `tests/test_menu_tune.py`: its
check of the compact bar's prompt line now reads the line with the Bug
report in it (the check is otherwise unchanged).
- Unchanged: nothing is sent anywhere; no saves, no game files, not
`hookshot_options.ini` or `hookshot_env.txt` themselves; no new option
or switch; the logs' own rotation; the screenshot path.

## How to try it

Insert menu (Insert, F1 or Esc, or the menu button) → **Gameplay** →
**Bug report** → Enter or A.
The row reads Saved and its help names the folder:
`bug-reports/<date>_<time>` in the game folder, with `report.txt`,
`hookshot_log.txt`, `hookshot_log.1.txt` and `picture.png`.

## How it was tested

**2026-11-11, after the two reviews, head `a75f3ca5` on `main`
`ba6eef70`.** Rebased twice today: onto #926, then onto #2042, #2378,
#2447 and the rest. The conflicts, each kept on both sides: #926's
`shot_ask_record` beside the old readback (which is now gone); #2042's
Debug rows where the Bug report row goes before Restart; #2378's
`row_value_cell()` and #2447's share row, where the row's value cell and
prompt went (the row now follows the share row's pattern, above); a
forward declaration in `host/hos_main.c`. #2042's rules hold for the
row: it has no value, so `preset_exempt` does not apply
(`tests/test_preset_exempt.py` reads only rows with one), and the branch
reads no on/off switch. #2042 also took `TOTK_` out of the names
`hookshot_env.txt` takes; the report follows (the test compares the two
lists).

Environment: Omarchy (an Arch Linux), kernel 7.2.15-1-omarchy, RTX 4090
with NVIDIA 615.78.08, i9-13900K, 94 GB, g++ 16.2.1 and clang 23.1.3.

- The new test on the branch (`python -I -B tests/test_bug_report.py`,
with `--cxx g++` and with `--cxx clang++`; the same line from both):
  ```
bug report: ok (report.txt as the issue form, both logs redacted, the
picture, the long log, the terminal start, switch values, NUL bytes, the
folder's reason)
  ```
Against `main`'s source (the test copied into an export of `ba6eef70`;
with both compilers): it fails at its first step, the menu row:
  ```
  at = menu.index('{TAB_GAMEPLAY, "Bug report", nullptr')
  ValueError: substring not found
  ```
And the review's NUL case against the old log copy (`fgets` and
`line.back()`, put back on its own):
  ```
bug report: the copy of a log with NUL bytes differs: b'[hos host]
hookshot v2.1.0-rc.3-39-gbdfe09c (source 763271ad)\n[hos Main] fs:
mounted content: -> ~/Games\n[hos Main] map: KokiriForest_Child
(child)\n[hos Main] half a line'
  ```
It compiles `vk_bug_report.cpp` alone with a driver and writes reports
from a made-up game folder inside a made-up home folder
(`.../home/alice/Games/Hookshot/`), with paths of the home and of
`/run/media/alice/...` in the logs, map lines and a `CRASH:` line in the
run before's. It checks: the folder holds exactly the report, both logs
and the picture; no file names the home folder, the user as a folder or
the game folder's path (`alice123` and `Malice` stay);
`hardware_report.py`'s `section`, `classify` and `os_of` read the
version, `NVIDIA` / `RTX 40` and Linux from `report.txt`; the place is
the last map, and the run before's; the switches: values kept
(`HOS_HEADLESS=1`, `60`, `off`, `3840x2160`, `-1`, `1.5`) and left out
(a path, a drive path, a menu script, an IP address, a `host:port`, a
13-digit number, and numbers under ROOM, KEY, SERVER, USER and PASSWORD
names), none of those values anywhere in `report.txt`, `PATH` and a
token not listed, no `%3D` in the link; the run before's crash line; the
link's fields and its length (with 98 switches: within 2000, the options
and the count in it, every switch in `report.txt`); the menu's way (a
thread, one report at a time); no frame means no picture, said so; a
picture that comes after the report went without it is deleted; a start
from a terminal; two reports in one second; a 22 MB log cut to its first
and last part with its middle's map still found; a log with a NUL in a
line and 4 KB of NULs at its end copied byte for byte, the map after the
NUL found; a folder that cannot be made, with the system's reason; the
redaction's Windows cases (either slash, any case); this PC's system
line. And the wiring by text: the row and what its help promises, Save
in both prompt lines, the press, the picture asked of `shot_ask_next`
and copied from the game's frame without the menu, the host's `map:`
line, that the switches it lists are the names `hookshot_env.txt` takes
(`env_line_allowed`'s), the form's labels and ids. Eight runs at once at
load 280 all pass (the first version of the menu's case read the
report's state too late under load in the full suite; it now holds the
report until it has looked).
- The checks the review named and those that read the menu's rows, on
this head (with g++ and clang++ where they compile C++):
`test_capture_dimensions.py`, `test_capture_slot_ownership.py`,
`test_menu_env_overrides.py`, `test_menu_keys.py`,
`test_pipeline_share.py`, `test_menu_tune.py`,
`test_stick_dead_zone.py`, `test_preset_exempt.py` (62 rows),
`test_menu_env_on.py`, `test_env_on.py`, `test_fps_stats.py`,
`test_gpu_choice.py`, `test_menu_restart_slots.py`,
`test_mouse_settings.py`: all pass. `vk_bug_report.cpp` alone with
`-Wall -Wextra -Wpedantic -Werror`: no warning from either compiler.
- `python -I -B tests/run_all.py` on Linux, on this head:
  ```
  440 passed, 1 failed, 20 skipped in 600 s (linux, 32 at once)
  ```
The one failure is `test_recorder_sync.py`, which ran out of its 600 s
at load 250-320 (other work ran beside it) and touches nothing of this
branch. An earlier run of the whole suite on this branch failed
`test_bug_report.py` once under that load: its menu case read the
report's state too late (fixed in the test, above).
- Merged into the newest `main` (`fce53453`, nine commits later; it
merges cleanly): `test_bug_report.py` (both compilers),
`test_menu_tune.py`, `test_pipeline_share.py`, `test_menu_keys.py`,
`test_menu_env_overrides.py`, `test_preset_exempt.py` (63 rows),
`test_menu_restart_slots.py`, both capture tests: pass. `test_env_on.py`
fails there and on `fce53453` alone (`HOS_FPS_LOG
(host/oot_high_fps.c:15)`, from #2470), not from this branch.
- Windows: `vk_bug_report.cpp` with a small driver compiles and links
for x86_64-w64-mingw32 (clang 23 with llvm-mingw 20261104's headers and
libraries, `-Wall -Wextra -Werror`: a PE32+ console executable). Not
run.
- In the game, on a build of this head's code
(`v2.1.0-rc.3-177-g9c538c91 (source c4f2afbc)`; the head differs only in
two test files), headless, RTX 4090, `RX_VK_PRECOMPILE=0` (shaders
compiled when first used), load 200 to 320 (other work ran beside it),
the save loaded into Kokiri Forest and the menu script pressing
**Gameplay → Bug report**:

pixels (row 176), which an any-case byte search reads as a name; the PNG
holds only IHDR, IDAT and IEND chunks. The host name is in no text file
of either.
- Pictures (headless, 1280x720; the first two are the harness's shots
with the menu drawn in, the third the report's own file):

![1: the Bug report row selected, Press to save. 2: after Enter, Saved,
with the folder under the help. 3: that report's picture.png: the game's
frame without the
menu](https://gist.githubusercontent.com/mooki000/b86bd3f35969803fb032f71f035844f8/raw/a943230353c26f026eef40ea371a06b754cc084f/hookshot-bugreport-shotask.jpg)

1. br-menu3, the row before the press: **Bug report** selected, **Press
to save**, its help (what goes in; no saves or game files; nothing is
sent), the prompt bar **Save Enter**.
2. After Enter: **Saved**, and the paragraph under the help names the
folder (`bug-reports/2026-11-11_17-25-32`) and how to send it.
3. That report's `picture.png`, taken through `shot_ask` at present
3063: child Link and Navi on the path in Kokiri Forest, hearts and
minimap; no menu, not dimmed.

![4: after a kill -9 and a restart, Saved, with its folder under the
help. 5: that report's picture.png: the game's frame without the
menu](https://gist.githubusercontent.com/mooki000/b86bd3f35969803fb032f71f035844f8/raw/a943230353c26f026eef40ea371a06b754cc084f/hookshot-bugreport-aftercrash.jpg)

4. br-crash3, after the `kill -9` and the restart: **Saved**, the folder
`bug-reports/2026-11-11_17-13-48` under the help.
5. That report's `picture.png` (present 1772): Kokiri Forest from low
down, facing the bright sky, hearts and minimap; no menu.

- The `report.txt` the after-crash run wrote, as a player would attach
it (the switches are the test harness's: see which values are written
and which are left out):

Hookshot bug report, made by the Insert menu's Bug report on 2026-11-11 at 17:13.

To send it: open https://github.com/NotRexed/Hookshot/issues/new/choose and choose Game problem (or the link at the end of this file, which fills in the answers below), copy the answers below into the fields of the same names, say what happened, and drag the files of this folder, this one too, into the issue.

### Hookshot version

v2.1.0-rc.3-177-g9c538c91 (source c4f2afbc)

### Changes from the defaults

Every Insert menu option is at its default.
Switches set (the environment, hookshot_env.txt; a value only when it is a number or on/off, and never for a name with TOKEN, KEY, ROOM, SECRET, PASS, SERVER or USER in it):
HOOKSHOT_NO_UPDATE_CHECK=1
HOS_AUDIO=0
HOS_DISCORD=0
HOS_ENV_FILE=(value left out)
HOS_HEADLESS=1

RX_VK_SHOT_MENU=1
SDL_AUDIODRIVER=(value left out)
SDL_AUDIO_DRIVER=(value left out)
VK_DRIVER_FILES=(value left out)

### hookshot_log.txt

hookshot_log.txt: this run's log as it was when the report was made, 245 KB.
hookshot_log.1.txt: the run before's log (hookshot v2.1.0-rc.3-177-g9c538c91 (source c4f2afbc), last written 2026-11-11 17:12), 117 KB.
In both, the home folder is written ~ and the user's name <user>.

### Screenshots or video

picture.png: the game's picture when the report was made, without the menu.

### What this folder holds

report.txt (this file), hookshot_log.txt, hookshot_log.1.txt, picture.png. Nothing else from this PC: no saves, no game files, not the options file itself.

- The link's length, signed out (`curl`, dummy links to the form,
2026-11-10; nothing of this PC in them):

`return_to` |

  | 4000, 4500 | `%20` | 500 after the redirect |
| 6000 | `%20` | sign-in page, but `return_to` dropped (the answers

## Not tested

- **Windows, at run time.** The report's GPU line there
(`VkPhysicalDeviceDriverProperties` on a Windows driver), its CPU, RAM
and system line (`__cpuid`, `GlobalMemoryStatusEx`, `RtlGetVersion`,
Wine), the path of the log stderr writes to
(`GetFinalPathNameByHandleA`), `GetLastError`'s reason, the redaction of
real `C:\Users\...` logs, File Explorer: compiled and linked only.
- **A windowed run.** Only headless runs: the picture taken with a
window, HDR (a native HDR frame is copied to 8-bit as the control
bridge's shots are) and frame generation were not seen.
- **The link in a browser.** Not opened in a browser, signed out or
signed in, and no issue was opened from it; only `curl` signed out
(table above). That GitHub fills the form's fields from it is its
documented behaviour, not seen here.
- **A real crash's last lines in the game.** The after-crash run ended
its first start with `kill -9`, which leaves no `CRASH:` line, and under
that load the first start had not reached a map yet; the test covers the
`CRASH:` line and the run before's map with made-up logs.
- AMD and Intel drivers' `driverName`/`driverInfo` text (only NVIDIA's
was read; `hardware_report.py` classifies typical RADV, AMD and Intel
strings correctly when written by hand), a Steam Deck, the AppImage, and
the Linux Builder's Play button (since #2279 it gives the game its
`hookshot_log.txt` again, so the report finds this run's log there; not
run here).

## Risks

- **Something private in a report.** The home folder (as a whole folder;
on Windows either slash and any case) and the user's name as a folder of
any path are replaced in both logs; a switch's value is written only
when it is a number, a size or on/off and its name holds none of the
words above; other environment variables are not listed; a microphone
chosen by name is not named; no saves, no options or env file, no game
files go in. Guarded by the test (made-up home and user, Windows cases,
`alice123` kept, values kept and left out) and, on this machine's real
logs, by the read-back above. Not guarded: something private a log line
carries in another form (a game folder outside the home named after a
person, a machine name in a network path), or a future switch whose
secret is a short number under a name without those words.
- **A report written while the game is busy.** The press does only cheap
work on the menu's thread (flushing the log, reading the environment,
`/etc/os-release`, the device's properties, the menu's rows); copying
the logs and writing the folder run on a thread of their own, one report
at a time (a second press while it saves does nothing). This run's log
is copied as far as it was when the copy began. The picture is waited
for at most 3 s.
- **The picture.** It shares #926's queue (16 asks at most) and its one
readback: a control-bridge shot being read back delays the report's by a
present or two. Without a report nothing changes on the present path.
The control bridge's log line for a written shot also appears for the
report's picture (`vk: present N written to ... (the control bridge)`).
- **The `map:` line in every log.** It is written only when the map or
Link's age changes, from `oot_inventory_refresh` (at most every 500 ms,
where the age is already read). A log that a player posts now says where
he was; the names are the game's own map names, which the debug tools'
teleport lines already print.
- A crash that leaves no line (a kill, a freeze, a power cut): the run
before's log is attached, but nothing in it says how it ended. A game
that stops before its menu can be used cannot make a report; the readme
says to attach `hookshot_log.1.txt` by hand then.

## Overlaps

`pr_overlap.py --branch bug-report` (run on this head, 2026-11-11): 79
open pull requests touch one of these files; 73 merge cleanly with it.
The row stores nothing (no `Options` field, no ini key, no option id),
so no option id can clash. Six conflict in this branch's files, each
hunk read:

- #2417 (the menu in 16 languages): it wraps the menu's texts in
`i18n::tr(...)`, among them the lines of `measure_help`,
`row_value_cell`'s branch for rows without a value, the help line in
`draw_options` and the compact bar's prompt (and the same line in
`tests/test_menu_tune.py`), where this branch adds the Bug report beside
the share row. Whichever lands second wraps the Bug report's texts the
same way; both stay.
- #1521, #1864, #2105, #2459, #2479 (the readme): a row each after
Microphone in the menu table (#2459 moves the Microphone row), where
this branch adds the Bug report's row; both stay.
- #2317 (saves and settings in a per-user data folder, logs in `logs/`)
now merges cleanly, but overlaps in meaning: this branch finds the game
folder through `ini_path()` and the logs in the game folder; after #2317
the settings are in the data folder and the logs in `logs/`. Whichever
lands second moves those two reads to `game_folder()` and `log_path()`.

## Questions for you

1. Is the Insert menu the place you want this, and the game folder the
place for the reports (with #2317, the data folder or `logs/` could be)?
2. The report takes the strict reading of CONTRIBUTING.md on
`hookshot_env.txt` (names, and only harmless values). Should
CONTRIBUTING.md say so, next to the line that lists the file?
3. The link carries the form's one-line answers and, when short enough,
the options and the switches' names. Do you want it at all, or only
`report.txt` to copy from?
