They are not a fixed 76 bytes. The first int of each record is its length, and while most placements are 76, every track also has eight of 140, two of 80 and one of 336 - 560 on Paingod's. Striding a fixed 76 landed mid-record on those, and hunting forward for the next plausible quaternion then locked onto arbitrary bytes: that is where the impossible class ids came from, and the "resource id" 1065353216, which is 0x3F800000 - float 1.0. Reading the length instead, all eighteen tracks parse to exactly their declared instance count with no bytes left over. That is the check that was missing before. It does not change what gets drawn, because the extra records were never drawable anyway. It does mean the parse is no longer guessing.
Regenerating the reference pages
docs/vtv-presets.html and docs/tracks.html are generated from
assets/RP411/RPL4.RES, the gauge config, and the console's RPConfig.xml.
Both are committed, so this is only needed when the resource file changes.
Both need a resource listing from the original tool, which is the authority for resource ids — the directory can be walked in file order, but the ids have holes (this file leaves 53 and 56 unassigned) so the walk has to be aligned against the listing:
Release\RPL4TOOL.exe -l assets\RP411\RPL4.RES > listing.txt # ends in _getch(); close it
python tools\pages\extract_presets.py vtv.json listing.txt
python tools\pages\build_page.py vtv.json docs\vtv-presets.html
python tools\pages\build_tracks.py listing.txt docs\tracks.html
RPL4TOOL finishes with _getch() (RP_L4/RPL4TOOL.cpp), so with stdout
redirected it writes the whole listing and then waits for a keypress —
close it once the file stops growing.
What each reads
| script | reads | writes |
|---|---|---|
extract_presets.py |
RES, L4GAUGE.CFG, tools/console-config/RPConfig.xml, listing |

build_tracks.py reads the front end's own kMaps / kFootballMaps arrays
so the page cannot claim a track is offered when the menu does not offer it.
Two formats worth knowing
Control mappings. A vehicle's ControlsMappings List holds the resource
ids of its L4 and Thrustmaster streams. Streams are named plainly, so
there is nothing in a stream saying whose it is — resolve by id, never by
which vehicle name sits nearest in the file. Records are 24 bytes and carry
their own mode mask; bits 3–8 are ModePreset1..6.
Map instances. 76-byte records: class id at +0, position at +48, unit quaternion at +60. A few records are longer, so resync on an unexpected class id rather than trusting the stride. The quaternion doubles as a checksum — a mis-read almost never produces a unit one.
